WIST-94

The WIST-94 is a semi-automatic pistol produced in Poland.

Development
WIST-94 was designed at Military Institute of Armament Technology (WITU) under the code name Piryt. Two prototypes were made in 1992, which differ in the barrel locking system: Model A01 used a rotary-locking system and Model B01 using conventional, Browning type tilting barrel locking. B01 was the only one to complete testing but the development was temporarily halted due to the military cutting off funding. Financed by WITU and Prexer company, the project continued and in 1994 a new prototype was developed. Called WIST-94 it is based on the B01 prototype. The new pistol was chosen by the Polish military as its new standard sidearm.

Design details
The WIST-94 is a semi-automatic pistol chambered for 9mm Parabellum round. It uses the Browning cam-lug system of operation. The polygonal-rifled barrel is locked to the slide by three locking lugs machined into the upper part of the barrel. The frame is made from polymer plastic while the slide is constructed from steel. The trigger mechanism is similar to the one used in Glock pistols: striker-fired double-action-only (DAO). After racking the slide back and after each shot fired the striker is held semi-cocked allowing for lighter trigger pull than conventional double-action. The only safety used is an internal automatic firing pin safety that unlocks the firing pin only in the final stages of the trigger pull. The WIST-94 is fed by a 16 round magazine. The magazine release catch is reversible for use by left-handed shooter. The slide release lever is located at the left side of the gun. The sights are fixed and are have self-luminous tritium inserts for low-light situations. The WIST-94L is also equipped with a laser sight mounted in the upper part of trigger guard. The name of the hand gun sounds, in Polish, very similar to Vis.
