MULTIPURPOSE NON-LETHAL SELF-DEFENCE WEAPON PB-4-1ML "AXIS" CALIBRE 18X45MM

The OSA is a multi-purpose effective non-lethal self-defense weapon with a laser target marker. It is defined as a short-barreled, four-shot, 18x45mm calibre pistol designed for personal protection using a traumatic cartridge and a flash-bang cartridge. A signal and illumination cartridge may be used for crises.

The gun has a folding bundle of four incomplete chambers and a bedding breech. A special thick-walled steel cartridge case with a groove and electric primer forms a custom barrel for each cartridge chamber.

The gun has a central extractor and a laser target marker beam passes through its hollow axis. This is activated by a switch on the left side of the pistol body and is used for quick target acquisition. The auxiliary sight takes the form of a groove on the top of the cartridge bundle and is topped with a white ball sight.

The initiation of the electric firing of the cartridges is accomplished by a current pulse induced by a trigger-controlled pulse generator. The gun has no safety, which is replaced by the stiffness of the trigger return spring. (DAO system).

The weapon is designed for:

  • Members of the armed forces (Police, Army of the Czech Republic).
  • Members of security services and security agencies.
  • The needs of the mountain service, fire brigade, ambulance service, etc.
  • Self-defence and crises. The OSA weapon is classified under Act No. 119/2002 Coll. as a "B" category weapon. The weapon may only be purchased by the holder of a firearms licence or a firearms licence!
