The GSh-18 (Cyrillic: ГШ-18)is a 9 mm semi-automatic pistol developed in the early 1990s at the KBP Instrument Design Bureau in Tula. The pistol's name is derived from its designers—Gryazev and Shipunov, and the number 18 denotes the magazine capacity. It is also designed to fire the new Russian 9x19mm 7N21 and 7N31 (Cyrillic: 7Н21 and 7Н31) +P+ armor-piercing rounds.
For 2011, KPB Design Bureau make the announcement of a possible marketing of a civilian version of the GSH 18 with modified trigger and firing pin for Russian gun law compliance. This information was confirmed at the 2011 IWA show where a sample gun was displayed.
The GSh-18 is a short recoil-operated, locked breech pistol. The weapon has an unusual cam-rotated barrel with 10 locking lugs. The GSh-18 is striker-fired and features a pre-set trigger that pre-cocks the pistol when the slide recoils after firing a shot. The striker firing pin is then fully cocked by pulling the trigger back to the rear.
