The P99 is a semi-automatic pistol developed by the German company Carl Walther GmbH Sportwaffen of Ulm for law enforcement, security forces and the civilian shooting market as a replacement for the Walther P5 and the P88. Design work on this new generation sidearm began in 1994, and the handgun was presented in 1997 with series production commencing that same year. The weapon was first introduced chambered in 9x19mm Parabellum; subsequently, a version in .40 S&W was also developed primarily for the American market and unveiled in 1998. The pistol is used by the German Police of some federal states of Germany, the Polish Police and the Finnish Army's special forces and military police, where it carries the designation PIST 2003 (Pistooli 2003).
Kirill, a Russian Secret Service agent hired by Yuri Gretkov, used the P99 to attempt to kill Jason Bourne in the The Bourne Supremacy. His P99 is seen in the film fitted with a QPQ finished slide and a silencer. He manages to hit Bourne in the Shoulder with it from a overpass and is later seen using it to blow out most of the windows of Bourne's taxi.
