Payday 2 is the sequel to Payday: The Heist. As with the first game, players may join up to three others in a spree of robberies and other heists to earn money. Payday 2 noticeably features many changes from the first game, among other things the new skill tree. Each of the five trees (the Mastermind, Enforcer, Technician, Ghost, and Fugitive) focuses on differing specializations, though unlike the first game do not grant new weapons for level ups (aside from special examples like the portable saw). Weapons are instead unlocked to purchase by leveling up, which now is done with experience points instead of money. Money is used to buy new weapons, modifications, and masks, though it is divided between a player's "Offshore Account" (which comprises 80% of the money they earn in a heist) and spending cash (the other 20%), and only the spending cash can be used to buy weapons and addons.
The following weapons appear in the video game Payday 2
The game operates with the heister moving in with 2 weapons, and 2 weapons only. A primary and a secondary. Primaries consist of assault rifles, shotguns, and marksman rifles. Secondaries consist of pistols, machine pistols, and bizarrely, a few chopped down variants of some shotguns and assault rifles. Players can take ammo from enemies, but not weapons, ala SWAT 4 and other such tactical shooters.
Each weapon has its own customization options, though some like the Glock 17 barely have any and others like the M4A1 may have much more than others. In addition to shared items like suppressors, weapons also have their own sets of unique addons, such as extended magazines or different finishes or grips. Mods can be removed from these weapons for no charge, and the mod in question will not be lost, merely returned to the player's inventory. However, re-adding it will again requires money.
In addition to this, owners of the Gage Weapon Pack #1 DLC will be allowed to change the firing mode between fully automatic and semi-automatic on all applicable weapons, and unlock access to special addons that enable locking a weapon permanently in one fire mode. Owners of the Gage Weapon Pack #2 DLC will also have access to the machine guns as well as new knives. Owners of the Gage Mod Courier DLC will also be able to unlock a special set of modifications that are otherwise unobtainable. As a bonus, the pack also comes with extra reticles and colors for all sights, though players without the DLC will still be able to use all the colors and a few of the new reticles. In addition, every weapon DLC pack since (and a few heist DLCs) have had even more new guns and melee weapons, and have begun to lock weapon addons to specific achievements rather than random drops. Finally, a noteworthy addition from the Gage Shotgun Pack DLC is the option to use different shell types for any of the game's shotguns. All firearms in Payday 2 are capable of performing a "tactical reload" (i.e. reload when the magazine isn't emptied) in addition to the "dry" animation, though as is common with most contemporary non-tactical shooters, none of them retain the round currently in battery, meaning there is no "one round in the chamber".
As a final addition, starting with the October 22, 2014 patch, players with a specific skill set are also allowed to replace their primary with two dual-wielded pistols, though this obviously comes with penalties to aiming and recoil and can currently can only be done with a few pistols. Dual-wielding can be done by any player with enough perks in the Hitman perk deck unlocked, or by players who have the Akimbo skill from the Fugitive tree
As of Update #65 (The first person animation update) All base game guns (except for the Bronco .44) and some DLC weapons have received new first person animations, most notably new reloading animations. Also with this update magazines now actually have fully modeled bullets in them, on top of that, it's is possible to see the bullets in the transparent magazines of weapons such as the JP36, Commando 553, Kobus 90 etc.
Handguns
Beretta 92FS Centurion
The Beretta 92FS Centurion appears as the "Bernetti 9" and is unlocked at reputation level 6, and has an incorrect 14-round magazine. Presently, it is one of the seven pistols that can be dual-wielded. The name "B9-S" is visible on the slide, as a nod to the pistol's name from the first Payday

Brügger & Thomet TP9-US
The Brügger & Thomet TP9-US is unlocked at reputation level 19 and is known as the "CMP." It holds 30 rounds in a 20 rounds magazine. Some time after release, the TP9 was given a stubby foregrip
Modified Version.
Glock 17
The Glock 17 appears in-game as the "Chimano 88 Pistol". It is the default secondary weapon, and is rather weak though holds a fairly large 17-round magazine. Originally it could only use one of three suppressors, though a few more compatible parts have been added in patches. It is one of seven pistols that can be dual-wielded, and the dual-wield versions notably have much higher damage and other minor differences
Modified Version.
Glock 18C Generation 3
The Glock 18C Generation 3 is unlocked at reputation level 29 and, as in the first game, is known as the "STRYK 18c." It still features a high rate of fire, low power, and low accuracy and comes with a 20-round magazine and tan frame and slide. Notably, it is one of 3 select-fire capable guns in the game that does not get the fire-mode locking mods.
Modified Version.
Glock 22C Generation 3
The Glock 22C Generation 3 appears as a new gun added in the Election Day update (3/20/2014) and is named the "Chimano Custom", with the website render marking it as a .40 S&W model. It has a default magazine of 16 rounds and can be modified in most of the same ways as the Glock 18. It has a unique red front sight and a flared magazine well and an identical-colored frame to the Glock 18C. The Custom becomes a Glock 35 if equipped with the Long Slide modification. This is one of the seven pistols that can be dual-wielded
Modified Version.
Glock 26
The Glock 26 appears as a new gun added in the John Wick update (10/22/2014) and is named the "Chimano Compact". It correctly holds 10 rounds and presently is one of the seven pistols that can be dual-wielded. Unusually, its dual-wield version has even less reserve ammunition than the single one, despite most other pistols using double their normal ammunition amount when dual-wielded (likely done for balancing, as the single gun has 150 rounds total)

Glock 26 Akimbo

Heckler & Koch USP Tactical
The Heckler & Koch USP Tactical appears as the "Interceptor .45" and is automatically unlocked for purchase by joining the Payday 2 Official Steam Group. It is decently powerful and holds a 13-round magazine. It is one of seven pistols that can be dual-wielded (along with all variants below)
Modified Version.
Heckler & Koch USP Expert
The Heckler & Koch USP Expert is used if the USP Tactical is equipped with the Expert Slide modification.
Modified Version.
Heckler & Koch USP Match
The Heckler & Koch USP Match is used if the USP Tactical is equipped with the Match Slide modification. This noticeably changes the color of the USP's slide and darkens the frame slightly
Modified Version.
Springfield Armory XDM
The Springfield Armory XDM appears as the LEO pistol as part of the Butcher DLC along with the VHS-D2 rifle. Initially a Croatian design (as the HS2000), it has an 19-round magazine, which is correct for the 9mm version.The markings are inconsistent however, showing on the slide that the chambering is .40 S&W, but the ejection port markings show that is chambered for .45 ACP.
Modified Version.
IMI Desert Eagle Mark XIX
The IMI Desert Eagle Mark XIX appears under its popular nickname of "Deagle" and is unlocked at reputation level 36. It is exceptionally powerful and holds an incorrect 10-round magazine. It is one of the seven pistols that can be dual-wielded
Modified Version.
IMI Desert Eagle Mark XIX Akimbo
Modified Version.
Intratec TEC-9
An Intratec TEC-9 modified to allow for fully-automatic firing appears as the "Blaster 9mm" and is unlocked for purchase by buying the Hotline Miami DLC. It holds 20 rounds by default and operates in strange ways uncharacteristic of the real TEC-9.
The in-game weapon fires from a closed bolt, meaning that it was based on the US-import KG-9 model which was a forced redesign by the Bureau of Alcohol, Tobacco and Firearms and Explosives (ATF) before the weapon could be marketed in the United States. The closed bolt would make the full automatic conversion unfeasible, which is an intended feature of the forced redesign as to discourage users from illegally modifying their TEC-9s. It is also capable of selective-firing, which is a highly unusual trait, that few illegal gunsmiths would implement into a weapon when converting from semi to fully automatic. This also suggest that the Blaster was based partly on the Interdynamic MP9, the parent design of the TEC-9.
Modified Version.
Intratec AB-10
The Intratec AB-10 is used if the TEC-9 is equipped with the "Short Barrel" modification.
Modified Version.
Mauser C96 "Broomhandle"
The Mauser C96 "Broomhandle" appears as the "Broomstick" and is unlocked for purchase by buying the Gage Historical Pack DLC. The "Broomstick" has a rather high damage, but is hindered by its 10 round magazine.
The Mauser C96 carbine appears if the "Broomstick" is modified with the Precision Barrel and Holster Stock.
Modified Version.
SIG-Sauer P226R
The SIG-Sauer P226R appears as the "Signature .40" and is unlocked for purchase by buying the Gage Weapon Pack #01 DLC. In-game it does the same amount of damage as the Crosskill(Springfield Armory 1911 Lightweight Operator), but most, if not all, of its stats are better compared to the Crosskill. By default, the P226 holds 12 rounds and its extended magazine unusually has no concealment penalty (unlike those for most weapons)
Modified Version.
Single Action Army
The Single Action Army with wooden grips appears as the "Peacemaker .45" and is part of the Butcher's Western Pack DLC. By default it is the 7.5" "Cavalry" model, but the "Shootout Barrel" and "Precision Barrel" modifications turn it into the 5.5" "Artillery" and 12" "Buntline Special" models respectively. When firing the weapon, the player character will fan the hammer. The Single Action Army cannot be modified with other modifications, limited only to the two barrels stated above, a stock, and a pistol grip modification.
The in-game revolver operates in strange and bizarre ways not seen on the real Single Action Army. The weapon is absurdly powerful for an antique revolver of this caliber, massively dwarfing the Bronco .44 and Deagle in stopping power despite both of them faring the other way around in reality. The extractor rod on the Peacemaker is also never used to remove spent cartridges, the player character simply opens the loading gate and puts in fresh rounds, the fired casings, if any, will fall out on their own.
Springfield Armory 1911 Lightweight Operator
The Springfield Armory 1911 Lightweight Operator is unlocked at reputation level 2, and is much more customizable than the starting Glock. It is named the "Crosskill" as it was in the first game and has an incorrect 10-round magazine. It is one of the four pistols that can be dual-wielded
Modified Version.
Springfield Armory 1911 Lightweight Operator Akimbo
Modified Version.
Taurus Raging Bull
The Taurus Raging Bull returns from the first Payday, again known as the "Bronco .44" but now featuring its full-length barrel by default. It holds 6 rounds and is unlocked at reputation level 6, and is massively powerful. As of a recent patch, street cops can use this devastating weapon. It is also notably used by the female FBI Agent enemies in the Hoxton Breakout heist
Modified Version.
Taurus 4510PLYFS
The Taurus 4510PLYFS was added to the game as a Crimefest community milestone reward, for having 1 million members in the Payday 2 Steam group. It shoots the .410 Bore and holds 5 shells, and is classed by the game as a shotgun, so handgun skills have no effects on it. Thanks to sharing its accessories with the other shotguns, it can accept the Silent Killer suppressor, which logically wouldn't work due to the space between the barrel and cylinder
Modified Version.
Walther PP
Modifying a Walther PPK with the Long Slide turns it into a Walther PP.
Modified Version.
Walther PPK
The Walther PPK is available for purchase with the Armored Transport DLC and is known as the "Gruber Kurz" pistol. It is fairly weak but easy to conceal and incorrectly holds 14 rounds.
Modified Version.
Mateba 2006M
The Mateba 2006M was added into the game with the Alesso Heist DLC. It's called Matever .357 in game, a reference to the butchering of the manufacturer's name in the English dub of Ghost in the Shell Stand Alone Complex. It's chambered in .357 magnum and holds a correct 6 rounds.
Submachine Guns
Carl Gustav M/45
The Carl Gustav M/45 is named the "Swedish K SMG" in game and holds a 40-round magazine, though is inaccurate and carries only 80 total rounds. It is available for purchase to anyone who owns the Armored Transport DLC.
The in-game weapon is based on the military version of the M/45, as evident by the lack of a fire selector.
Modified Version.
Cobray M11/9
The Cobray M11/9 appears as the "Jacket's piece" and is unlocked for purchase by buying the Jacket Character Pack. It holds 32 rounds and has a foregrip.
Modified Version.
FN P90 TR
The FN P90 TR appears as the "Kobus 90" and is unlocked at reputation level 36. It has the highest magazine size of any secondary, though only carries two magazines total and it has only one unique accessory (its long barrel). As of the First Person Animations Update, the P90's magazine is now translucent and visibly empties as the gun is fired
Modified Version.
FN PS90
Modifying a P90 with a Long Barrel and the semi auto trigger lock turns it into a FN PS90.
Modified Version.
Heckler & Koch UMP45
The Heckler & Koch UMP45 is used only by some NPCs, namely the GenSec Elite SWAT and the Murkywater PMC enemies. It is unavailable for player use at the present time
Heckler & Koch MP5A4
The Heckler & Koch MP5A4 returns from Payday: The Heist, again known as the "Compact-5" and still in use by some SWAT units. It is unlocked at reputation level 13 and can be changed into various other configurations with modifications. It holds 30 rounds.
Modified Version.
Heckler & Koch MP5A5
The Heckler & Koch MP5A5 is used if the MP5A4 is equipped with the "Adjustable Stock" modification.
Modified Version.
Heckler & Koch MP5SD5
The Heckler & Koch MP5SD5 is used if the MP5A4 is equipped with "The Ninja Foregrip"
Modified Version.
Heckler & Koch MP5SD6
The Heckler & Koch MP5SD6 is used if the MP5A4 is equipped with both The "Ninja Foregrip" and the "Adjustable Stock".
Modified Version.
Heckler & Koch MP5KA4
The Heckler & Koch MP5KA4 is used if the MP5A4 is equipped with the "Bare Essentials" stock and "Sehr Kurze Foregrip", though this version has rails instead of the default grip.
Modified Version.
Heckler & Koch MP5/10 and MP5/40
The Heckler & Koch MP5/10 and MP5/40 equipped with the Adjustable Stock is used only by Cloaker special units. Oddly, it seems to make the same sounds as an unsuppressed MP5 despite clearly having a suppressor.
With the Straight Magazine modification offered by The Butcher's Mod Pack 2, player-owned Compact-5s can also impersonate the MP5/10 and MP5/40, even gaining the appropriate damage upgrade and recoil. The impersonation is imperfect, however, due to the Compact-5 still lacking the bolt release function of the MP5/10 and MP5/40 and the magazine is not the proprietary type provided by Heckler & Koch.
Heckler & Koch MP7A2
The Heckler & Koch MP7A2 appears as the "Spec Ops" and is unlocked for purchase by buying the Gage Weapon Pack #01 DLC. It comes with its 20-round magazine by default
Modified Version.
IMI Uzi
The IMI Uzi appears as the "Uzi" and is unlocked for purchase by buying the Hotline Miami DLC. It holds 30 rounds and comes equipped with the distinctive "K" foregrip by default.
Modified Version.
Ingram MAC-10
The Ingram MAC-10 is known as the "Mark 10" and is unlocked at reputation level 2. It has an incorrect magazine size of 40 rounds in a 20 rounds magazine.
Modified Version.
Sa. Vz.61 Skorpion
The Sa. Vz.61 Skorpion appears as the "Cobra" and is unlocked for purchase by buying the Hotline Miami DLC. Its "Extended Magazine" modification is odd, increasing the magazine size from 20 to 40 rounds despite simply being a second magazine attached to the side of the first one
Modified Version.
Sterling L2A1
The Sterling L2A1 appears as the "Patchett L2A1" and is unlocked for purchase by buying the Gage Historical Pack DLC. It also holds an incorrect 20 bullets in standard magazine, but the weapon is the most powerful SMG.
Modified Version.
Sterling L34A1
The Sterling L34A1 is used if the Sterling L2A1 is equipped with the "Supressed Barrel" modification. Like the Sterling L2A1, it incorrectly holds 20 rounds which can be modified to the full 30.
Modified Version.
Thompson M1928A1
The Thompson M1928A1 with a 50-round "L" drum magazine was added in the December 3, 2014 patch and is unlocked at level 14 for members of the Payday 2 Steam group. Along with the P90, it has the highest magazine size of any SMG in the game, but its accuracy and damage are rather low without modifications. It is one of 3 select-fire guns (one of two secondaries, alongside the Glock 18) that does not get the fire-mode locking mods.
Modified Version.
Assault Rifles / Battle Rifles
Bofors Ak 5
The whole Bofors Ak 5 family appears as the AK5, all packed inside one gun's upgrade selection. Its accuracy and recoil are solid from the start, but the low damage needs help to reach its best - which isn't stellar. Unlocked at level 33.
Ak 5B
Sticking on the "Bertil Stock" from the designated marksman model turns the AK5 into an ersatz Bofors Ak 5B.
Ak 5C
The modernized Bofors Ak 5C comes together by replacing almost everything that comes off the receiver.
FN FNC
The "Belgian Heat" handguard is cribbed straight off the FN Herstal FNC in a direct reference to Lt. Vincent Hanna (Al Pacino) from the movie Heat.
Colt M4A1
The Colt M4A1 appears as the "CAR-4" and is unlocked at reputation level 4. Essentially it is an upgrade of the starting Model 733 and features tan flip-up ironsights by default. It is frequently used by law enforcers and holds 30 rounds, without any magazine modifications. The NPC-exclusive model for this weapon features some small differences from player-used ones, such as a different location for mounting a laser pointer. As in the first Payday, this weapon is still used by SWAT Snipers, despite there being more appropriate weapon models available
Modified Version.
Colt M16A4
The Colt M16A4 with a short barrel appears as the "AMR-16" and is unlocked at reputation level 39. It is shown with a safe/semi/auto selective fire capability, meaning it was based on the export International Model R0901, and incorrectly holds 30 rounds in a 20 rounds magazine. It can be equipped with an M16A1 handguard with the Blast From The Past modification. Unlike the other AR-15 type rifles, the M16's gas block and front sight disappear when using optics.
Modified Version.
Colt Model 733
The Colt Model 733, fitted with an A2-style receiver and 6-position stock, appears as the AMCAR, the very first primary weapon. Its damage output is outright miserable compared to every other long arm and little can be done to fix it. Dumped as soon as possible, but kept by few as a voluntary handicap. Given the influence of Heat on the production, the highly specific choice of model probably isn't a coincidence.
Enfield L85A2
The Enfield L85A2 was added alongside the Clover Character Pack as the "Queen's Wrath". Notably, it is the only select-fire capable primary (and one of three select-fire guns available in the entire game) that does not get the fire-mode locking mods. By default it holds 30 rounds and has a very long reload time
Modified Version.
FAMAS F1
The FAMAS F1 appears as the "Clarion" rifle and is unlocked for purchase by buying the Gage Assault Pack DLC. It incorrectly holds 30 rounds.
Modified Version.
FAMAS G1
The FAMAS G1 is used if the "G2 Grip" is equipped to the FAMAS F1 (Before Update #37, "G2 Grip" is called "Retro Grip" although the FAMAS G1 is newer model of FAMAS F1). Like FAMAS F1, It incorrectly holds 30 rounds.
Modified Version.
FN Herstal FAL
The FN Herstal FAL appears as the "Falcon" rifle and is available to purchase for owners of the Big Bank DLC. It holds 20 rounds and is a very flexible weapon. Notably, the FAL was the first weapon to have its accessories linked to DLC achievements rather than random drops
Modified Version.
DSA SA58 OSW
The FAL can become a DSA SA58 OSW by the "CQB Foregrip" "Tactical Grip" and "CQB Stock" modification.
IMI Romat
Attaching the "Retro Foregrip" to the FAL allows it to impersonate the IMI Romat (although the FAL buttstock and barrel remain the same).
FN Herstal SCAR-H
The FN SCAR-H STD appears as the "Eagle Heavy" rifle and is available to purchase for owners of the Gage Weapon Pack #1 DLC. It holds 20 rounds and is a powerful weapon. A version with a modified stock is used by some Murkywater PMC enemies
Heckler & Koch G3
The Heckler & Koch G3 appears as the "Gewehr 3" rifle and is available to purchase for owners of the Gage Assault Pack DLC. It holds 20 rounds and has a long reload time, and can be made to resemble a PSG-1 with the correct parts
Heckler & Koch G36K
The Heckler & Koch G36K makes an appearance as the JP36, unlocked as early as level 16. The damage output stays mediocre no matter what, but its main draws are easy recoil, solid accuracy and a deep 180 round ammo pool.
H&K G36C
Installing the "Compact Foregrip" turns the gun into a convincing G36C.
HS Produkt VHS-D2
The HS Produkt VHS-D2 was released as part of the Dragan Character Pack DLC, much like the L85 was part of Clover's DLC. It is known internally as the "Lion's Roar", has a high rate of fire and overall good stats, though it has a long reload time and if unmodified, high recoil.
Modified Version.
HS Produkt VHS-K2
The Lion's Roar becomes the HS Produkt VHS-K2 when equipped with the Short Barrel.
IMI Galil ARM
The 7.62mm variants of IMI Galil ARM appears as the "Gecko 7.62" rifle and is available to purchase for owners of the Gage Assault Pack DLC. It incorrectly holds 30 rounds and is shown with an unusable bipod extended
IMI Galil MAR
The 7.62mm variants of IMI Galil MAR is used if the Galil ARM is equipped with the "CQB Foregrip" and "Skeletal Stock" modification. Like Galil ARM, It incorrectly holds 30 rounds.
IMI Galil Sniper Rifle
The IMI Galil Sniper Rifle is used if the Galil ARM is equipped with the "Sniper Foregrip" and "Sniper Stock" modification. Like Galil ARM, It incorrectly holds 30 rounds.
Izhmash AKMS
The Izhmash AKMS appears as the "AK.762" and is unlocked at reputation level 16. Holds 30 rounds and less total ammunition than the AK-74. A golden version of this weapon with diamond plating on the wooden handguard was released as a community reward, though is more expensive and has a lower concealment stat with no other differences
Modified Version.
Izhmash AKMSU
A variant on the Izhmash AKMSU is unlocked at reputation level 29 and is named the "Krinkov," the nickname of the AKS-74U. It holds 30 rounds and is a secondary weapon, rather than a primary like the other two Kalashnikov rifles.
Modified Version.
Izhmash AKS-74
The Izhmash AKS-74 is the second primary weapon unlocked, at reputation level 1. It appears simply as the "AK" and holds 30 rounds.
Modified Version.
Kel-Tec Sub 2000
Introduced in the Golden Grin update as a farewell gift from the Dentist, the Sub 2000 appears as the Cavity 9mm. A unique weapon to put it in gentle terms, it is a pistol-sized primary weapon that achieves the damage level of a light sniper rifle using 9x19mm rounds. It fires exclusively in semiauto, a first since the old update that introduced different fire modes.
Sub 2000 Gen 2
Slapping on the "Appalachian Foregrip" transforms the first-run gun into a current Gen 2 model.
Olympic Arms K23
The Para SMG is unlocked at reputation level 19. A very competent and modifiable gun, it can easily cover whatever a gimmick primary weapon might lack - like a pocket CAR-4, albeit with worse concealability potential. It is a confusing mix of half-dozen different ultra-short AR-15 pistols and carbines, but since the game assets label it as "olympia", that's the headline.
Olympic Arms K23B
The basic look of the gun is closest to the OA K23B ultrashort carbine. However, the removable carry handle and RIS are featured only in its sister OA K23B Tactical, the emergency wire stock is taken from an M231 FPW and the original aluminium foregrip has been extended over the gas block to make it a dead ringer with a round-front type La France M16K. The name itself may be a dim reference to the fact that most of the involved guns have 9x19mm variants as well, but that's reaching.
Attaching a Milspec Magazine and a Standard Stock bring the Olympic Arms K23B closest to its retail shape.
Olympic Arms K23P
Buying a Bare Essentials Stock for extra concealment removes the wire stock and leaves only the buffer tube behind. This combined with the old A2 flash hider out it as the Olympic Arms K23P, a semiauto pistol version of the same caliber.
M4 CQBR / Mk 18 Mod 0
Attaching a Medium Barrel for extra accuracy and replacing the basic handguard with something else makes the Para finally look like an actual assault rifle. However, the barrel's rather specific ~10" length (falls just short of the 11.5" AMCAR) makes the most American option the Mk. 18 Mod 0, ignoring the gas block/front sight being all wrong.
Romanian AIMR
Attaching the "AK Slavic Dragon Barrel" to the Izhmash AK's and allows it to impersonate the Romanian AIMR (although the AKMS stock remain the same).
SIG SG 552-2
The SIG SG 552-2 appears as the "Commando 553" (referring to the SG553 instead) and is available to purchase by anyone who owns the Armored Transport DLC. It Holds 30 rounds. The rifle can be confirmed as a 552-2 by the permanent scope rail and the simple, folding front and rear iron sights instead of the original sights of the SIG assault rifle series. As of the First Person Animations Update, the weapon's magazine is translucent and visibly empties when firing, rather than being solid brown
Modified Version.
Springfield Armory M1A SOCOM 16
The Springfield Armory M1A SOCOM 16 with a McMillan M2A stock appears as the "M308" as in the first Payday. It is semi-automatic by default and holds 10 rounds. Prior to the first Gage Weapon Pack release, it was semi-automatic only, making it the only assault rifle to have the mode
The Steyr AUG A2 is at reputation level 8 and is named the "UAR" (presumably short for Universal Army Rifle). It holds 30 rounds and is rather accurate and powerful. It can be fitted with a railed fore end to make it resemble an AUG A3, but the rifle still lacks the bolt release of an A3.
Upon launch, the rifle can be seen using a Magpul PMAG, which suggests it was not based entirely on an authentic AUG. After the animation update, however, it gains the AUG's proprietary magazine.
Modified Version.
Thales F90
Attaching the "Raptor Polymer Body" lower receiver added in Butcher Mod Pack #2 update to the AUG A2 allows it to impersonate the Thales F90 (although still lacks the bolt release of an F90).
Z-M LR 300ML
The CAR-4 fitted with the "Aftermarket Special" handguard, "Folding Stock" and "Short Barrel" closely impersonates the Z-M LR 300ML, though not completely as the pistol grip remains the M4A1's, the handguard is not a perfect copy, and it still lacks the LR 300's gas block.
AS Val
The AS Val was added with the Sokol character pack. It can be modified into the VSS vintorez if the solid stock is applied.
Shotguns
MPS AA-12 CQB
Added with the release of The Butcher's BBQ Pack was an MPS AA-12 CQB as evident by its short barrel, known internally as the "Steakout 12G". Comes with a default capacity of 8 shells, an unusable shell rack and entirely fictional semi/auto selective fire capability as all extant AA-12 models are capable of fully automatic fire only. Its in-game rate of fire of 300 matches that of the real weapon.
Optional enhancements includes a 20-round drum, a long barrel and custom integral suppressor.
MPS AA-12
The "Steakout 12G" becomes a regular AA-12 when fitted with the Long Barrel mod.
Sentinel Arms Striker-12
The humble fixed-drum Striker-12 appears by the family's most prestigious name; the Street Sweeper. In Overkill's usual fashion, it's a mix of all of the different versions mooshed together in a highly educated, equal measure. Unlocked at level 33, it's very capable of terminating an entire room of FBI SWAT in one 12-shot sweep, but the low damage needs specialization help to cope with Maximum Response teams. It was the only secondary-class shotgun introduced by Gage's Shotgun Pack.
Benelli M4 NFA
The Benelli M4 NFA is used when the M1014 is equipped with the Short Barrel and Collapsed Stock
Modified Version.
Benelli M4 NFA Tactical
The Benelli M4 NFA Tactical is used if the M1014 is equipped with the Short Barrel and Solid Stock
Benelli M4 Super 90
The Benelli M4 Super 90. Named the "M1014" in-game. First introduced in the Death Wish Update in the hands of some GenSec Elite SWATs, though with a fixed stock. A player-usable version was finally added in the Gage Shotgun Pack DLC. It holds 8 shells by default
Modified Version.
Benelli M4 Tactical
The Benelli M4 Tactical is used if the M1014 is equipped with the Solid Stock
Beretta S3/CZ Redhead Deluxe hybrid
The Beretta S3 O/U/CZ Redhead Deluxe O/U. An over/under shotgun introduced with (free) Bonnie character pack March 13th appears to be a hybrid of the Beretta S3 O/U and CZ Redhead Deluxe O/U. Named the "Joceline O/U 12G" in-game.
Double Barrel Shotgun
The Double Barrel Shotgun appears as the "Mosconi 12G" and is unlocked at reputation level 39. Obviously it only holds two shells but is one of the most powerful weapons in the game. Has only two modifications, "Road Warrior" and "Gangsta Special," both of which saw down the barrels and stock respectively
Modified Version.

Izhmash Saiga 12K
The Izhmash Saiga 12K appears as the ninth primary weapon, and is shown as being fully-automatic with select fire available. Prior to the Gage Shotgun Pack DLC, it was the only semi-auto shotgun in the game. The model is not based on an actual Saiga 12K, but is rather a hybrid taking several components from the AKMS. Firstly it features a standard ribbed AKMS top cover, rather than the smooth cover used on the Saiga which has a larger ejection port with a sprung sliding cover over the rear portion. Secondly it has an under-folding AKMS stock which was not available on the Saiga. Lastly the receiver is a hybrid of an AKMS one and a Saiga, with the magazine release being immediately ahead of the trigger guard and receiver dimples above the magazine, but with a Saiga 12 style front trunion (lacking the corresponding rivets however). It is named the "IZHMA 12G" and is unlocked at reputation level 26 and holds 7 shells. It is notably used by a Bulldozer variant called the "Killdozer" that wears black armor. His model of Saiga uniquely has an unobtainable solid stock, and before it was removed in a patch, a drum magazine

Winchester Model 1873
The Winchester Model 1873 appears in the game as the "Repeater 1874" and is part of the "Butchers Western Pack" DLC. Oddly enough, despite being chambered entirely for pistol-grade ammunition types, it is classified as a sniper rifle, and thus can penetrate thin walls and shields. Like the Mosin-Nagant it can use, and starts out with, iron sights. It can be modified with a long barrel, suppressed barrel, and a unique magnified scope. However, it can not be customized with modern modifications like lasers and sights besides the one unique to it.
Others
C4
C4 can only be used with the right Technician skills. By default, it is used as tripmines, which can be used to set traps for enemies. The tripmines themselves are unlocked simply by starting to learn Technician skills. The later Shaped Charge skill allows players with it to use their explosives to instead blow up doors and safe doors, potentially saving a lot of time for them and their team. Certain skills also allow them to be toggled into 'Sensor Mode' in which they will not explode, but will mark enemies that pass by. This can be useful in stealth runs. Some C4 packs are also used for certain objectives, and can be used by any player when picked up
Heckler & Koch MP5K
The Heckler & Koch MP5K appears as part of the Technician's Sentry Gun deployable, seen inside a case. As in the first game, the Sentry Gun can be destroyed by enemies and will shut down when its ammunition supply is exhausted.

M18 Smoke Grenade
The M18 smoke grenade is used by law enforcers at times. The Commissar in Hotline Miami also uses one when fought
M67 Hand Grenade
The M67 hand grenade is only usable by players with the first Gage Weapon Pack DLC, unless they buy the Grenade Case for their team during a heist. Grenades have a fairly wide blast radius that can go through walls, and they will stun enemies that aren't killed outright. Players can carry up to three and should be careful, as they can easily cause civilian kills or friendly fire if handled improperly. Notably, it's possible for enemies to shoot the grenades in mid-air, causing immediate detonation. All grenades are shown with the red Overkill bomb logo painted on the side.
M79 Grenade Launcher
Unlike the original Payday, the M79 Grenade Launcher was not included at release, but was added in the Gage Assault Pack. Known as the GL40 in game, it holds a single grenade in the chamber and the player can carry a maximum of 6 shots at once. Like the M67 it has friendly fire and can easily kill civilians unintentionally. Like its previous incarnation, grenades fired by the M79 in Payday 2 does not have a minimum arming range, and can detonate immediately upon being shot if the player is facing an obstacle.
The front leaf sight on the M79 model acts as an in-built gadget, and pressing the enable gadget key (default "G"), allows the player to fire grenades at a much higher arc than usual.
Milkor MGL Mk 1S
Added with the release of The Butcher's BBQ Pack DLC was a Milkor MGL Mk 1S, known internally as the "Piglet" grenade launcher. It has similar damage per shot to the M79 but boasts a wider range of modifications and much larger ammo pool.
Model 24 Stielhandgranate
The Model 24 Stielhandgranate was added to the game in the Gage Historical Pack, and is referred to in game as the "Potato Masher". Unlike the M67, it is not used as a thrown explosive, but rather as a melee weapon, similar to the Demoman from Team Fortress 2.
RPG-7
The RPG-7 was added in the Overkill Pack DLC, and has the highest damage of any weapon in the game at an astounding 10000, but can only carry 4 rounds at a time. The weapon is unaffected by ammo pickups and can easily incapacitate the user and their whole team if fired recklessly

Hand Held M134 Minigun
The Hand Held M134 Minigun was added in the Overkill Pack DLC, and has the highest rate-of-fire of any weapon. It holds a total of 750 rounds, and has to be refilled via ammo bag deployables.
