Abstract

The invention discloses a compressed gas-operated pistol (1) with a gas capsule (15) arranged in a grip member (5), which is in operative connection with a valve system (33) of the pistol (1). The secure receipt and piercing of the gas capsule (15) is effected through an abutment (17) which completes an inherent displacement and an external displacement superimposed on this inherent displacement. The external displacement is thereby effected by a support element (23) of the abutment (17) which is contacted by capsule tensioner (25). (FIG. 2).
