Features

The Udav pistol is a short recoil-operated, semi-automatic handgun. It uses a traditional Browning-type action with a tilting barrel that locks into the ejection opening in the slide. The trigger is of double action type, with an exposed hammer and ambidextrous safety levers on the slide. When engaged, the safety also automatically lowers (decocks) the hammer. The pistol features a polymer frame with a steel insert molded into it. There is no manual slide release lever.

The slide hold-open device is automatically disengaged to chamber a fresh round as soon as a new, loaded magazine is inserted into the grip. This pistol uses double stack, double feed magazines holding 18 rounds. The magazine release button is ambidextrous and located at the base of the trigger guard. For special operations, the Udav pistol can be equipped with an extended threaded barrel to accept a detachable sound suppressor (silencer). It also features a built-in rail under the barrel, forward of the trigger-guard for the easy attachment of lights or aiming devices.

The gun fires 7N42 armor-piercing rounds and 7U4 cartridges with reduced bullet velocity.https://tass.com/defense/1543145
