Sloan (Morgan Freeman) is seen armed with a M712 "Schnellfeuer" or "Fastfire", the selective fire version of the C96 "Broomhandle" Mauser with a detachable box magazine instead of a fixed internal magazine loaded with stripper clips when preparing to kill Wesley Gibson (James McAvoy) at his work place, only to discover he has been tricked by a decoy and is sniped by Wesley from an incredible distance.
Safari Arms Matchmaster
Fox (Angelina Jolie) packs a custom Safari Arms Matchmaster 1911 clone with an extended 12 round magazine, titanium Yanek compensator, engraved ivory grips, and custom engraving throughout the film. The official website of the film describes: "Fox's weapon of choice is a custom .45 calibre SAFARI MATCHMASTER semi automatic pistol. Although she prefers its lightweight versatility, she is a virtuoso with any firearm which exists".
CornerShot
During the shootout at the pharmacy, Fox (Angelina Jolie) uses a CornerShot device together with her Matchmaster, allowing her to look and shoot around corners during the shootout with Cross (Thomas Kretschmann) in the grocery store. It's obviously based on the real CornerShot, but there isn't a type like the one used in the film.
Heckler & Koch USP Compact
Wesley (James McAvoy) uses a Heckler & Koch USP Compact for his first two kills and his first bullet curve. He also briefly uses one during the final gunfight at the textile mill. It could be called his main weapon or his weapon of choice.
Star Ultrastar
When Wesley (James McAvoy) nearly falls from the derailed train, he is caught by Cross (Thomas Kretschmann). Shortly thereafter, he pulls a Star Ultrastar from his waistband and kills Cross with a single shot to the chest. Informed of his deception by both the dying Cross and Fox (Angelina Jolie), he fires a shot into a window he's kneeling on to escape Fox, falling into the river below as a result. He is briefly seen using it during the mill shootout as well.
Custom Beretta 92S
Mr. X's (David O'Hara) sidearm used in the opening sequence is a customised Beretta 92S. It has ornate grips and a compensator.
Later it is given to Wesley (James McAvoy) to shoot the wings off of flies, to prove he is gifted. Sloan (Morgan Freeman) refers to it as an "Imanishi 17," though no known make or model of firearm exists. Wesley hides the Beretta in the toilet and after leaving it there to soak for about a week, he retrieves it and uses it while chasing Cross ([[ through the parking garage, accidentally shooting The Exterminator (Konstantin Khabensky) instead. He then uses it for the shootout on the train with Cross, firing several shots at him before he drops it during the crash and draws his Star Ultrastar. After soaking in water for so long, the gun would not likely be in firing condition, nor would the ammunition be dry enough to fire.
Jericho 941 "Baby Eagle"
Pekwarsky (Terence Stamp) uses a tutone (stainless frame, blued slide) Jericho 941 "Baby Eagle" to hold on Wesley in the castle. Full black Baby Eagles are also seen in the hands of multiple other people, usually just briefly as continuity errors. Wesley most notabley uses several during the Mill shootout, one of which he uses to kill The Butcher (Dato Bakhtadze) by firing a steel poker rod into him after he acidentally jams it down the muzzle of the gun. In reality, this would not fire the rod like a big bullet, but become an obstruction and blow up the gun.
Jericho 941FB Compact
Cross (Thomas Kretschmann) uses a Jericho 941FB Compact "Baby Eagle" as his weapon of choice in the film. The rounds his gun are shown firing are far too large to be chambered in the breech or to fit in the magazine.
Cross (Thomas Kretschmann) uses a made up fantasy sniper rifle built from one of the flintlock/matchlock hybrids to kill Mr. X in the begining of the film, using a telescope along with the rifle scope to aim at such an incredible distance. At the end of the film, Wesley uses this rifle to kill Sloan. To portray the flight path of the unique bullet, the bullet's path is rewinded until it reaches the rifle again.
Heckler & Koch UMP-9
Heckler & Koch UMPs are used by some of The Fraternity guards outside the textile mill and one in the mill during the final gunfight when Wesley grabs it from him for quick use. They are noted as the 9mm model based on their curved magazines.
Taurus Raging Bull
Fox draws and fires a Taurus Raging Bull at Cross during the car chase. One of the assassin's in the library is also seen armed with a Taurus Raging Bull fitted with a red-dot sight.
Cross is seen trying to fire a Heckler & Koch MP7A1 with a reflex sight "pistol style", meaning stock retracted, foregrip folded like a handgun while chasing after Fox and Wesley in her car. Wesley is also seen briefly firing one in The Fraternity mill, which strangely changed from a Heckler & Koch UMP-9.
Unknown Pistol
The Gunsmith and another various assassin in The Fraternity library are seen with unknown long-slide handguns mocked up to look like a side-loader, one of which loads from the right, the other from the left.
Reminton Rolling Block 1871 Cavalary (mock-up)
Seen among the weapons table when Wesley trains on the range is a Remington Rolling Block 1871 Cavalry pistol mocked up like a modern gun by adding a relex sight and attaching an AK magazine.
Ruger Super Redhawk
A Ruger Super Redhawk with a 9 1/2" barrel and scope is seen on the table of weaponry.
SIG-Sauer P226R
Two SIG-Sauer P226R pistols, one K-kote, one Nickel, are seen on the weapons table.
Not sure
I can assume it's an M4, but the rail system in front makes me think it's the barrett REC7.
No way. The REC7 was just introduced this year. The movie came out this year, but it would have been filmed last year. Unless the film's armorers time-traveled to this year, there's no way a REC7 can be in this movie.
Ok, then maybe a 416? From this shot, it appears to be a flat top similiar to a 416
Film producers can get their hands on prototypes before the model is released so it could still be an REC7 but im still not too sure.
Only if they intend to use it prominently (as a "hero" weapon) and therefore give the manufacturer an advertisement. I'm pretty sure that having some anonymous henchman use it briefly wouldn't qualify as such. Also, the "producers" don't get weapons for the movie - that's the job of the property master and armorer.
It's simply an M4 with an A.R.M.S. selective integrated rail system. you can see it being attached to the top of the receiver with screws, so it can't be a Barrett REC7 where the handguard is attached like a standard handguard.
Glock 19
The NYPD uses a Glock 19 so I am pretty sure it is one, it looks kinda compact too.
Double Barrel Shotgun
G3
The Second Picture is that of a G3/SG1, just without a scope, you can tell from the cheek rest, though someone removed the rear sight spindle.
Wheel-lock Guns
Mr. X at the beginning of the movie is seen curving the bullet with one.
These are ancient wheel-lock pistols. Probably German made. Wesley attempts to kill Sloan with one of these but is shot by fox, and the gun fell off his hand.
unknown revolver
Wesley picks up this revolver and kills the Repairman with it, then stabs it through his head and uses him as a shield while still firing the revolver through his skull.
Taurus PT99
A Stainless PT99 is used by Sloan to show Wesley how to curve a bullet.
