Mafia III is an open-world action-adventure video game, and a sequel to Mafia II. It is developed by Hangar 13 and published by 2K Games, and was released in October 2016 for the PC, Xbox One and PlayStation 4.
The following weapons appear in the video game Mafia III:
Unlike Vito in Mafia II and his hammerspace inventory, the inventory system returns to a limited space inventory, with only one long gun and one smaller weapon able to be carried at a time, like the first Mafia game. This inventory system returns in the subsequent game, Mafia: Definitive Edition.
Ammo has also been simplified as while a handful of weapons use their own ammo, most weapons now share ammo in certain internal "catagories" such as all non-revolver handguns sharing ammo, revolvers having their own ammo types and all submachine guns sharing ammo.
Handguns
AMP Auto Mag Model 180
The AMP Auto Mag Model 180 appears as the "Clipper .44" and is rewarded by Thomas Burke for the third racket takeover. It is mildly anachronistic for the game's late 1960s setting, as AMT didn't begin producing AutoMags until 1970. Oddly, the gun's icon in the UI is a Wildey Magnum.
Beretta Model 70 (unusable)
A Beretta Model 70 is held by a Playmate model on the cover of the November 1965 issue of Playboy, which can be collected in-game.
Browning Hi-Power
The Browning Hi-Power is available for use in the game as the "Elling 9mm" and used heavily by mobsters in Tickfaw Harbor, Downtown, and Barclay Mills. It can also be seen among other weapons in a stash from one of the promotional videos.
Colt Commander (not usable)
Donovan uses what appears to be a Colt Commander with a suppressor in the main game final cutscene. This pistol is, like the Tokarev, not player-usable.
Colt M1911A1
The Colt M1911A1 is one of many available handguns in Mafia III, known as the "Masterson Pistol". There are two silenced variants in-game, the first being the "Silenced Masterson" which is given as a favor from Vito Scaletta during his first racket takeover. The second is "Silentium", which is the same stat wise as the normal silenced M1911 but with fancy engraving that comes with the "Judge, Jury & Executioner" weapon pack DLC. No matter what pistol Lincoln is carrying, during cut scenes he will be seen with the M1911.

Silentium
Colt Python
Known as the "Masterson Phoenix". Lincoln Clay and late game mobsters make use of the Colt Python throughout the game. A special skinned copy is available for My2K users known as "Il Duca" (The Duke in Italian).
Scoped Colt Python
The scoped Python is rewarded as a favor from Vito Scaletta during the third racket takeover.
Il Duca
Diana 5G Air Pistol
An air pistol resembling a Diana 5G Air Pistol is found in-game as the "Dormer B128", used as a tranquilizer gun for Bounty Hunting missions added in the Stones Unturned DLC.
High Standard HDM
The High Standard HDM is usable throughout the game as the "Silenced Deacon .22" after unlocking a turf for Thomas Burke. It has an integral suppressor, allowing for more stealthy gunplay.
MAB PAP F1
The MAB PAP F1 appears as the "Blackburn FAF-33" as the highest tier semi-auto handgun, commonly used by mobsters in the late game areas of the French Ward, Frisco Fields, and Southdowns. One is found near the M60 at the Federal Bank during the prologue.
Smith & Wesson 39
The Smith & Wesson 39 is known in-game as the "Alfredsson M419". It's given free when the arms dealer van becomes available and very commonly used by enemy mobsters in areas such as Delray Hollow, Pointe Verdun, and River Row, and by the Federal Bank guards in the prologue.
Smith & Wesson Model 19
The Smith & Wesson Model 19 appears in-game as the "Alfredsson M200", the standard sidearm of New Bordeaux's Police Department and an uncommon sight with mobsters. The M200 does only 38% damage per shot, compared to the Phoenix's 47%, implying that the former is used with .38 and the latter with .357 Magnum.
It is also seen in a cutscene, held by Alma as she checks the cylinder.
Tokarev TT-33 (unusable)
Connor Aldridge uses a pre-1947 Tokarev TT-33 with an aftermarket and anachronistic muzzle brake in the Stones Unturned DLC as his sidearm of choice. The pistol is unusable by the player.
Shotguns
All shotguns, when hip-fired, play a pump racking sound after each shot, even including the lever action 1887, break action Lupara and the semi auto 1100.
Ithaca 37
The Ithaca 37 appears in-game as the "Cornell 40", used by mid-game mobsters.
Mossberg 500
The Mossberg 500 with an extended magazine tube appears as "Riot 550" and used by late-game mobsters.
Remington 870
A "Barker 390" pump-action shotgun can be used and is commonly found with low level mobsters. It appears to be a Remington 870, and not the Mossberg 500AT some have claimed it to be, by the rounded trigger guard and the shorter magazine cap.
Remington Model 1100
The Remington Model 1100 appears as the "Barker 1500 Tactical", given as a favor by Cassandra during the fifth racket takeover.
Sawed-off double barrel shotgun
The classic Lupara appears in-game as the "Lupara" as one of the two sidearm shotguns.
"Barker 390 (Gator Skin)"
Supposedly a customized variant of the "Barker 390" (Remington 870) shotgun in the base game, the shotgun that comes with the Family Kickback Pack appears to be a mash-up of the in-game Remington 870 (receiver, magazine, and barrel) and Mossberg 500 (safety, triggerguard, and furniture). The result is vaguely reminiscent of the (anachronistic) Mossberg 590.
Winchester Model 1887
A Winchester Model 1887 resembling the configuration from Terminator 2 is available for use in Mafia III, and a rare sight with mid game mafia goons as a sidearm shotgun. Lincoln can flip-cock the gun in a manner similar to Arnold Schwarzenegger albeit with one thumb given the smaller lever loop. It appears as the "Elmwood 1925" with a special version with the Judge, Jury & Executioner Weapon Pack, the "Exterminatore".
Exterminatore
Submachine Guns
Beretta M12
The Beretta M12 appears in the game as "Carter M33-A", rarely used by mid-game mafiosos.
Heckler & Koch MP54
The Heckler & Koch MP54 appears in-game, modeled on the very first MP5 prototype, the MP54. It appears in the game as "Deutsche M11B" and is acquired as a favor from Cassandra for the third racket takeover. While the MP54 isn't necessarily anachronistic, it was first adopted by the German Federal Police in 1966, which is two years prior to the game's setting, it's more or less anachronistic to see in the hands of random street thugs in 1968. The HUD icon wrongly displays the gun with folded stock and different muzzle.
M1A1 Thompson
The M1A1 Thompson appears in-game as the "Trench 1938" and used heavily by early game enemies. With the "Family Kick-back" pre-order pack, a special version of the M1A1 was included called the "Trench 1938 Drum" , having a vertical grip much like the earlier M1921 Thompsons, but still built into the M1A1-style forestock. In the cutscene for the mission "Fish need to eat", Vito is seen using a M1A1, despite using an AKM in gameplay. Some M1A1s are also seen used by Hmong fighters in a stock footage scene.

M3 Grease Gun
The M3 "Grease Gun" appears as the "M1N8", used primarily by mobsters in the mid-game. A suppressed version is offered by Cassandra in the first racket takeover as a favor.
The MAC-10 appears as the "Suppressed Mk 1020", given to Lincoln during the Faster, Baby! DLC and available to purchase from the Arms Dealer after finishing the final mission.
Uzi
The Uzi appears in the game as the "Binya", a late-game single handed SMG rarely wielded by mafiosos and in certain locations.
Sa. Vz.61 Skorpion
The Sa. Vz.61 Skorpion appears in game as the "Czech Ver. Ba-65", rarely used by mobsters in the early game and one of the first sidearm SMGs available for use.
Smith & Wesson 76
The Smith & Wesson 76 SMG appears in the game as the "Alfredsson M833" available from the Arms Dealer as a slower ROF alternative to the Thompson.
Rifles
AKM
An AKM appears in-game as the "Pasadena AR30" and serves as the automatic weapon of choice for late game mafia goons. It's a mixture of both AKM and AK-47 parts, such as an AK-47 pistol grip, slab-side handguard and milled receiver but an AKM front sight post, gas block and ribbed receiver cover.
Is notably used by Vito Scaletta and Roman "The Butcher" Barbieri.
A version painted black with tribal markings appears as the "Black Sacrament", rewarded for completing the Signs Of The Times DLC.
Colt M16A1
The Colt M16A1 appears in-game as the "Stromer .223" as a favor from Burke during the fifth racket takeover or in a CIA safehouse in the Stones Unturned DLC.
M1 Carbine
The M1 Carbine appears as the "Hartmann .30" and is commonly used by mafia goons in the early game. It appears without a bayonet lug, common on early civilian pattern guns such as Universal Firearms carbines. A heavily embellished version comes with the Judge, Jury and Executioner Weapon Pack, known as the "Praecisione .30".
One also appears in the hands of a Hmong fighter in stock footage.
Praecisione .30
M1 Garand
A M1 Garand appears in-game as the "Mayweather .30" and commonly found on mid-game NPCs. Oddly the weapons description claims it replaced the in-game M1 Carbine analogue, rather than having both serve side by side like in real life.
Some Garands are also seen used by US Army soldiers in stock footage during a cutscene explaining Father James's backstory.
M14
The M14 appears as the "Automat SG" and is used by late-game mobsters although it does spawn in a few early game locations. It's notable for using its own separate ammo type, so you can only get ammo from other M14s with it.
Despite not appearing in the game in any form, John Donovan mentions the XM21 semiautomatic variant by name in a mission cutscene.
M14 with night vision sight
An M14 fitted with a AN/PVS2 Starlight scope appears as a sniper rifle, the "Hawk 4540 Night Vision" as a favor from Vito for the fifth racket takeover.
Lee-Enfield No.1 Mk III (unusable)
The Lee-Enfield No.1 Mk. III appears in stock footage in the hands of some Irish soldiers in a cutscene about Burke's backstory.
Sniper Rifles
Springfield M1903A1
The Springfield M1903A1 appears in-game as the "Mayweather M04A3" and is commonly used by Racket Enforcers in the mid-game.
Tokarev SVT-40
The Tokarev SVT-40 appears as the "Viper 55", used by late game Racket Enforcers.
Winchester Model 70
The Winchester Model 70 appears in-game as the "Manitou Model 67" as the primary weapon of Racket Enforcers in the early game. A special version appears with camo wrapping with the Family Kickback DLC, fittingly named the "Camo Model 67".
Winchester Model 70 Camo Version
Machine Guns
Browning M2 Heavy Barrel
The Browning M2 Heavy Barrel appears in-game in the Stones Unturned DLC as part of mounted turrets found during the DLC's campaign. One can also be mounted to the Mohican Scout truck. In the base game, they can be seen mounted on M3 Half Tracks in stock footage during a cutscene explaining Father James's backstory.
M1918A2 BAR (unusable)
In a stock footage scene explaining John Donovan's activities in South East Asia, we can see a Hmong fighter holding a M1918A2 BAR.
M60
The M60 appears as the "Hartmann 7.62", first used during the prologue robbery on the Federal Reserve and finally as Vito's favor for the final racket takeover.
Grenades & Explosives
M67 hand grenade
The M67 hand grenade appears in-game as the "Frag Grenade", acquired with the first level of "IRA Bomber" and frequently dropped by mid to late game NPCs.
Mk. 2 grenades
One of the cutscene talking about Vito Scaletta shows a picture of him in the Army during WWII with an Mk 2 hand grenade affixed to his uniform, with the picture taken from Mafia II.
C4
C4 charges appear in-game when Lincoln rigs up certain objects in enemy rackets to blow. Actual charges can be acquired after acquiring the second level of the "IRA Bomber" perk.
Dynamite
Dynamite appears in certain black market shipments found in rackets in-game.
Unknown Mine
An unknown Mine was added with the Stones Unturned DLC.
Launchers
China Lake Launcher
The China Lake Launcher appears as the "GL KORSKY", added with the Stones Unturned DLC.
M72A1 LAW
The M72 LAW appears as the "Hartmann AT-40" as Cassandra's final favor for the last racket in-game, although it does appear in the Royal Hotel before that.
M79 grenade launcher
The M79 grenade launcher appears as the "Hartmann HLP", acquired through Burke's final favor for the last racket.
RPG-7
The RPG-7 appears as the "RPG KORSKY", added with the Stones Unturned DLC.
