The Bourne Identity (2002)

SIG Sauer Pro SP2009

SIG Pro SP 2009 9mm

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 Sauer SP2009 pistol. Shortly thereafter, he takes the passports and money and leaves the gun in the box. He also gets ahold of another SP2009 briefly while at the US Consulate in Zurich after agents attempt to take him into custody. Bourne tosses the gun in a trash can while making his escape.

Colt M16 & variants

When Bourne escapes the embassy, U.S. Marines armed with M16s, M4s and other variants of that series commence a room-by-room office sweep.

Micro Galil

When Bourne is in his apartment, the assassin (code-named Castel) who breaks through the window uses a Micro Galil to try and kill Bourne and Marie.

SIG SG 550 Sniper

The Professor (Clive Owen) uses a SIG SG 550 Sniper variant 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 (Franka Potente) to Marie's stepbrother's place of residence.

Unidentified Side by Side Shotgun

Used by Jason Bourne after The Professor tracks him and Marie to the farmhouse in the French countryside. It appears to be a hammerless, box lock action, side by side shotgun with a Churchill or Uplander stock and a splinter fore end. No other details can be made out.

CZ 100

The Professor draws a CZ 100 from his carry bag when he is unable to locate Jason Bourne while in the fields behind the home of Eamon (Tim Dutton), Marie Kreutz's friend in the French countryside.
