The "Walther" P99 Self-loading Pistol's development began in 1994 by "Carl Walther" company. The main development idea was to design a self-loading pistol suitable for self-defense and law enforcement forces both. Pistol's predecessor the "Walther" P88 had a very similar characteristics. Unfortunately the P88 was not very popular. "Walther" company recommended oneself as a developer of high quality and reliable pistols.
Pistol automatic works on barrel short return principle. Unlike the classical self-loading pistols P99 has no external hammer. It's mechanism works in "single-action" and "double-action" hammer modes both. This feature makes it safe and ready to use. The P99 has four safety mechanisms. Pistol executes only single fire. There is striker cocking indicator at the rear side. It can be seen or felt. Pistol is fitted with decocker as well.Military model of the "Walther" P99 Self-loading Pistol.

Barrel and all other metal parts are coated, what provides high all weather resistance and long service life.
Pistol is fed from a high capacity magazines (9 x 19 mm model). However there is a ability to use 10 rounds magazines intended for self-defense. High, two line capacity magazines increase pistol's fire power and combat abilities.
