The Bourne Identity (2002)

Sig Sauer 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 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.

Sig Sauer SG550 Sniper

The Professor (Clive Owen) uses a Sig Sauer SG550 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 (Matt Damon) and Marie Kreutz (Franka Potente) to Marie's brother's place of residence.

Walther P5 Compact

The Professor (Clive Owen) draws a Walther P5 Compact from his carry bag when he is unable to locate Jason Bourne (Matt Damon) while in the fields behind Marie Kreutz's (Franka Potente) brother's home, in the French countryside. After his death at the hands of Bourne, Bourne takes the weapon and later uses it in the Treadstone safe house in Paris.
