A Swiss policeman carries a SIG-Sauer P225, of which Bourne swiftly disarms him and disassembles.
SIG Pro SP2009
When Jason Bourne (Matt Damon) visits the bank in Zurich, he gets ahold of his safety deposit box and, inside, finds several passports, cash and a SIG Pro SP2009 pistol. Shortly thereafter, he takes the passports and money and leaves the gun in the box.
Heckler & Koch MP5K
During the search for Bourne in the U.S. Embassy in Zurich, the Marine Staff Sergeant can be briefly seen with a Heckler & Koch MP5K. (This is a continuity error, as he was carrying an M16 variant in other shots).
M16/AR-15
U.S. Marines arm themselves with various M16/AR-15-model assault rifles when searching for Bourne in the U.S. Embassy in Zurich. Strangely, all of the rifles seen in this scene appear to be civilian AR-15 variants, many of which are clearly "post-ban" versions (if you look on the armory wall, you can see many lack flash hiders and bayonet lugs - all signs of the "politically correct" black rifles that used to be sold in American gun shops). The ones with the short barrels are Bushmaster "Dissipator" carbines, an AR-15 variant that used to be sold only to LE agencies, but is now available to civilians in most states since the Assault Weapon Ban ended.
SIG-Sauer P229
A U.S. Embassy worker carries a black SIG-Sauer P229, which Bourne manages to take from him during a struggle. Bourne tosses the gun in a trash can while making his escape.
This is a mistake as DSS agents still use the SIG P228.
Well then it's a real life continuity error, as that is clearly a P229, as told by the milled slide. ~Yournamehere
Taurus PT945
Castel (Nicky Naude) has a blued Taurus PT945 in his case with his passports and money. He is never seen using it. One of the assassins in the Paris Treadstone safehouse also has a suppressed stainless PT945, which Bourne disarms him of. Bourne then fires the PT945 and Walther P5C akimbo, but the PT945 is upside down because he took it from the assassin very quickly and didn't have time to adjust his grip.
Micro Galil
When Bourne is in his apartment, Castel (Nicky Naude) breaks through the window, firing a Micro Galil, to try and kill Bourne and Marie.
SIG 550 Sniper
The Professor (Clive Owen) uses a SIG SG 550 Sniper as his weapon of choice, assassinating Nykwana Wombosi (Adewale Akinnuoye-Agbaje) in Paris with it. He is seen with the rifle again later in the French countryside, after he tracks down Jason Bourne and Marie Kreutz to Marie's stepbrother's home.
unidentified side-by-side shotgun
Jason Bourne (Matt Damon) uses an unidentified 12 Gauge Double Barreled Shotgun belonging to Eamon (Tim Duttin) to search for and shoot the Professor, after the Professor tracks him and Marie to the farmhouse in the French countryside. It appears to be a hammerless, side by side shotgun with a box lock action and a Churchill or Uplander stock and a splinter fore end. No other details can be made out.
Walther P5 Compact
Jason Bourne carries a Walther P5 Compact in the Treadstone safe house in Paris after taking it from the Professor (Clive Owen). After disarming an assassin with armed a suppressed Taurus PT945, Bourne uniquely carries the P5C and the PT945 akimbo.
CZ-100
The Professor's (Clive Owen) gun from his carry bag changes from a Walther P5C to a CZ-100 when it is seen in the snow (continuity error).
unidentified pistol
Conklin (Chris Cooper) pulls this pistol from Nicky Parsons' (Julia Stiles) field kit in the Treadstone safehouse in Paris to confront Bourne.
It almost looks to me like a Makarov, though it would be highly unusual for a CIA operative to use such a gun. -MT2008
This could be a CZ83...that had a shape similar to a Makarov. ----Clutch 03:46, 5 February 2009 (UTC)
During the flashbacks to his mission to kill Wombosi (Adewale Akinnuoye-Agbaje), Jason Bourne (Matt Damon) is seen holding a Glock 19 fitted with a laser sight to Wombosi's head.
SIG SG 552
One of the Treadstone guards fires a SIG SG 552 at Bourne on the safehouse staircase. Bourne dispatches him with a single shot from the P5C.
Beretta 92FS
Manheim (Russell Levy) uses a suppressed Beretta 92FS to shoot Conklin outside the Treadstone safe house in Paris.
Yea, the front sight is missing...-Winchester (1-26-09)
I know it's hard to see at night, but is it just me or does this look more like a Beretta 92FS Inox? Notice how the slide is darker than the suppressor.
I don't think so. Also, do you mean, the slide is lighter than the suppressor? -MT2008
