Frank Castle (Thomas Jane) uses a pair of heavily customized M1911A1]]s as his main sidearms in the film. His father Frank Castle Sr. (Roy Scheider) devoted some dialogue to the guns, commenting on how he bored the chambers, customized the triggers, and added some thread-on compensators. Though the pistols are refered to as colts, they are likely not colts. Colts have a the colt name machined into the left hand side of the slide, these do not have any markings on the slide. The only part that could possibly be of colt manufacture would be the frame, however an experienced pistolsmith would likely start with a better quality after market frame for a build such as this. Some of the other noticable feattures are their Novak night sights, the Smith and Alexander extended magazine wells, combat hammer and combat triggers, Kings Gun Works extended slide stop and extended slide releases, as well as Ed Brown Memory Grove beavertail grip safeties and front cocking serrations.
M4A1
Frank Castle is seen using an M4A1 fitted with an M203 grenade launcher and an aimpoint M68 red-dot sight when assaulting Howard Saint's club Saints and Sinners. He loses use of this weapon when a bullet from enemy fire hits the reciever and ruins the gun.
Special
LeMat 1861
Seen in Castle Sr.'s gun case is a LeMat 1861 percussion revolver.
Colt 1851 Navy
Seen in Castle Sr.'s gun case is a Colt 1851 Navy percussion revolver.
Castle's M4A1 is seen fitted with an M203 grenade launcher, which do to such close proximity battles is never used during the shootout in the club. The original movie poster also prominently feattures Castle holding an M16A2 fitted with an M203.
Cobray M79LF
Seen next to the M203 launcher in Castle's arsenal is what appear to be a Cobray M79LF flare launcher with the stock folded up.
Doesn't look like a cobray, but more like a K.A.S. system itself, the trigger and grip don't match the cobray style or placement, suggest revising.
Beretta 92FS Inox (flashpaper)
Howard Saint (John Travolta) is seen using a Beretta 92FS Inox "Flashpaper" gun, which is designed to imitate the flash and smoke of a blank gun minus the loud sound and dangerous wad which fires from the barrel. Instead of swapping to a real Beretta, it appears to stay a flash-paper gun throughout the film, so I'm seperating it from the real Inoxes used.
Beretta 92FS Inox
The stainless steel Beretta 92FS Inox makes several appearances in the film in the hands of nameless thugs. The most notable user is Dante (Marc Macaulay), one of Saint's hired thugs, who tries to draw it when facing Castle with Spoon (Terry Loughlin) at his side in the Saint building.
Ruger SP101
One of the money launderers in the Saint Building tries to draw a Ruger SP101 revolver when Castle walks in.
Heckler & Koch G36C
When Bobby Saint (James Carpinello) tries to impress his father by buying guns, he meets with Otto Kreig (Frank Castle under-cover), who shows Bobby 4 suitcases loaded with Heckler & Koch G36C assault rifles. I didn't bother adding all 4 suitcases because it looks like they just reuse the same shot 4 times and flipped it twice.
Colt Officers ACP
When the FBI raids the weapons transfer, Otto Kreig (Frank Castle under-cover) draws a tutone Colt Officers ACP which apears to be customized, before being "killed".
Micro Uzi
Several of Micro Uzis are seen used by Saint's men when they massacre Castle's family. Most notabley seen using them are Dante and Spoon when they both fire their Micros at Maria Castle's (Samantha Mathis) car, and manages to flip it with them.
Mossberg 500 (sawed-off)
When Saint's men massacre Castle's family, one of the hitters is armed with a sawed-off Mossberg 500 shotgun, which looks to be a smooth-bore gun based on the raises ribbing for adding a sight (which is usually used for bird guns to make swing-shooting easier.) Castle picks up this hitter's Mossberg and arrives too late to save his wife and son, finding them dead on the docks after being run over. When the people who killed them pull back around in their Ford pickup truck, Castle fires off four shots, which pattern like buckshot rounds, before running dry. When Castle first begins firing, he clearly racks a live round from the chamber, which would have greatly helped him out when he faces the men as they exit the truck. While the ribbing on the barrel is usually used for bird guns, it is not likely used as a one because bird shotguns have a 2 round cut-off in the mag tub (making a round in the chamber 3 rounds, the maximum capacity allowed for bird hunters)[A removable plug is used]. Since the gun is clearly seen loaded with 5 rounds, it is assumed it is used precisely as a gun to fire buckshot. (Then again, most bird hunters don't used sawed-off shotguns anyway).
Mossberg 590 "Compact Cruiser"
When Castle goes to the Saint Building to dump all his money into the street, he takes a Mossberg 590 "Compact Crusier", which is the perfect gun to stash in his trench coat. He uses the gun to force Saint's money launderers to dump the money from the top floor and "rain 100 dollar bills."
Ithaca 37 (pistol gripped)
Lincoln (Tom Nowicki) uses an Ithaca 37 shotgun with nickel plating and a pistol grip throughout the film. It is not a Stakeout model, as it is too long. When using it to shoot Castle's vest in the dance club, he puts two 12 gauge rounds into his body armor from less than 10ft away. Though this might seem impossible, a level IIIA Vest can easily withstand shots as powerful as 00 Buckshot.
Intratec TEC-9
Some of the hitters who help massacre Castle's family are armed with TEC-9s, which clearly have sling swivels (although these shots don't show them), which a TEC-DC9 lacks. They were likely converted to full-auto by the armorer for the film.
Savage/Stevens 311A
When the hitters begin to massacre Castle's family, Castle Sr. takes out two Savage/Stevens 311As for himself and Frank. The two both uses them to great effect and Castle scores two kills with his, one of which by means of blowing up a propane tank on a grill. They are smooth-bore shotguns because they are clearly seen loading birdshot shotgun rounds into them. Based on slight difference in the trigger guard and pistol grip/tang area, these appear to be Spanish Eibar copies.
Sawed-Off Savage/Stevens 311A
Castle appears to saw down one of his 311As later in the film, and turns it into a sawed-off shotgun. Castle brings this gun with him when he raids Saint's club, holstered on his back, and manages to kill one of his thugs with it.
Steyr SPP
Several thugs in the film are seen armed with Steyr SPP pistols, which appear to be converted to full-auto based on the one instance it is seen firing.
Heckler & Koch USP45
Spoon (Terry Loughlin) is seen with a Heckler & Koch USP handgun in his holster when facing Castle in the Saint building. Based on the length of the grip, it looks the the .45 ACP model, the USP45.
Cobray M11/9
One of the arms dealers is armed with a Cobray M11/9 when the FBI raids the exchange. Bobby Saint points his gun at him by mistake and is shot by him in return.
Walther PPK
Bobby Saint (James Carpinello) keeps a stainless steel Walther PPK as his weapon. He is killed before he ever gets a chance to use it.
Glock 17
The Glock 17 2nd generation is seen multiple times in the film by nameless thugs but is most notabley seen used by Jimmy Weeks (A. Russell Andrews), who they delve deeper into character-wise in the extended cut.
Glock 18
One of the weapons seen in Castle's arsenal is a chrome slide Glock 18 3rd Generation. (while it is not confirmed as a Glock 18, the 33 round magazine and stock indicate it possibly is.) Sadly, he is never seen using it despite being seen preparing it before leaving to assault Saint's club.
Glock 19
One of the thugs in Saint's dance club is seen using a compact Glock 19 2nd generation, which based on the angle appears too short to be the same Glock 17 used in other scenes.
Harry Heck (Mark Collie) is seen using what looks like an Armsel Protecta to fire shots at Castle's Pontiac GTO, but he luckily has metal shields that slide up over the windows to protect himself.
I counted 13 shots, but I thought Armsel Strikers carried 12 rounds?
Harry Heck's Revolver
Harry Heck ditches his Striker when Castle totals his GTO and gets out, armed with a BFG. The revolver is a Dan Wesson most likely 44 Magnum or 45 Long Colt. The characteristics of this revolver can be noted by the curve of the hammer, cylinder release on the crane, vented rib barrel, and the small hole noted on the bottom of the grip where a grip stud is used to hold the grip to the frame, and barrel nut noted at the muzzel. Dan Wessons where at one time considered the most accurate out of the box revolvers one could get, and had been the top winning revolvers in IHMSA competitions. Castle pulls out a spring loaded stilleto and fires it into his neck before he can use it. Castle than takes the gun and leaves in Heck's Plymouth Roadrunner.
Heckler & Koch MP5A5
Some of the FBI agents that make the illegal weapons sale bust are armed with Heckler & Koch MP5A5 submachine guns.
Heckler & Koch MP5SD4
One of the FBI agents is seen firing a Heckler & Koch MP5SD4, which is a full-stock MP5A4 with an integral sound suppressor.
Smith & Wesson Model 66
When Castle is "safe-guarding" his apartment, he places a stainless steel Smith & Wesson Model 66 into a custom made drawer launcher, which kicks out the drawer when the counter is tapped. Castle tries to grab this gun when he is attacked by "The Russian" (Kevin Nash), but he grabs a weight and smashes the barrel flat.
SIG-Sauer P226
John Saint (James Carpinello) uses a nickel-plated SIG-Sauer P226 throughout the film. He most notabley uses it when he puts a bullet in Castle's chest, claiming "This time they're not blanks."
Heckler & Koch P2000SK
One of the thugs in the club is seen armed with a Heckler & Koch P2000SK and tries to use it before he recieves a .45 between the eyes from Castle.
Taurus Snub
Castle is seen in the extended cut giving Jimmy Weeks (A. Russell Andrews) an unknown Taurus Snub (It looks like a Model 605, but has a Smith & Wesson genuine adjustable sight). Weeks takes the gun and tries to kill Castle, but the gun is empty. Castle gives Weeks a single bullet and watches as he commits suicide for ratting him out to Saint and having his family killed because of it.
M16A2
On the original movie poster for the film, Castle is seen armed with an M16A2 assault rifle fitted with an M203 grenade launcher.
M18A1 Claymore
Castle has an M18A1 Claymore anti-personal mine among his arsenal, and uses one with a beeper detonator to blow up one of Saint's money transporting boats.
M67 "Baseball" Hand Grenade
Among the weapons in his arsenal, Castle has a handful of M67 hand grenades, one of which he keeps attached under the sink in his bathroom. He also keeps a switch near by which shuts the door so he can throw the grenade out and shut the door to protect himself from the blast. This technique proves inefective when he tries it on The Russian, who uses a pipe like a baseball bat and whacks the "baseball" right back into the bathroom. Castle just barely makes it into the bathtub to avoid the blast.
Unknown AP Mines
Castle brings some Anti-Personel (AP) mines with him to assault the dance club. One he plants on the main entrance, which is set off when someone tries to run out. The second mine he sends up the dumb-waiter hidden in a wine bucket. When the man goes to pull the wine out, the whole rooms blows up. The last mine he uses to leave John Saint at the mercy of his own willpower. He claims the AP mine weighs 8lbs, which isn't much, but then he outstretches his arm and ties the fuse to a hanging piece of insolation. He then says how holding that mine up with an outstretched arm would be a "hell of a work out."
Unknown Remote Mines
Castle brings an unfathomable number of Remote Detonation mines with him, which he plants on all the cars in the parking lot. When he sets them all off, a sky view reveals "The Punisher" skull drawn with flame.
Compound Bow
While not a firearm, Castle does some nice stealth kills with a compound bow. Anyone who knows what type is welcome to comment.
ANIMATED SEGMENT
An extra on the extended cut is an animated segment built to illustrate the deleted scene of Frank Castle serving in the Gulf War, during a battle in Kuwait. The following guns are seen in this segment.
Behind the scenes note: The weapons used in the flashback animated sequence were a mix of airsoft, metal replica, and a few real guns. The soldiers shot on green screen were airsofters, not actors, and not real military.
I recon the 92 elite was an airsoft gun, as you can have the safety down and the hammer back on those.
AK-47
During the deleted animated segment taking place in Kuwait, an enemy soldier can be seen firing a gun that vaguely resembles an AK-47.
Beretta 92G Elite II
Seen in the hands of a U.S. officer is a Beretta 92G Elite II. He is seen loading it up and then it disapears, being replaced by a simpler M9. The 92G Elite II was not issued during the Gulf War nor was it even made yet so that's somewhat of an anachronism.
Colt Model 723
Some of the U.S. soldiers are seen firing Colt Model 723 carbines. Some of the enemies are seen using them as well.
M14
A U.S. soldier is seen firing an M14 Rifle briefly.
Some U.S. soldiers are seen armed with Heckler & Koch MP5SD3s. Castle is briefly seen firing one.
Remington 870
Some U.S. soldiers are seen with a folding stock Remington 870 shotgun and Castle grabs one and charges an enemy position with it.
Colt Model 715
One of the enemy soldiers is seen firing an M16 with an A1 sight but with an A2 reciever, making it a Colt Model 715.
Norinco Type 69 RPG
An enemy soldier is seen firing an Norinco Type 69 RPG with an over-sized warhead. It can be most easily identified by its single grip and carry handle as opposed to the dual grips on an RPG-7.
Beretta M9
A Beretta M9 is seen used by the U.S. officer to attempt to kill the captured enemy soldiers but he is stopped by Castle.
M26 "Lemon" Hand Grenade
A U.S. soldier is seen with a M26 "Lemon" hand grenade on his belt, which the enemy prisoner pulls off his belt and commits suicide with, killing everyone but Castle and Weeks.
