Abstract: A gas pressure pistol, particularly a sports pistol, comprises a compressed gas container, which is disposed below the barrel and which via a passage that is adapted to be closed by a valve communicates with the rear end of the barrel, also comprises a bolt, which is guided in a housing and is adapted to be retracted from the rear end of the barrel, and a trigger mechanism, which is accommodated in the housing and comprises a trigger lever, which is pivotally movable in a pull-off sense, a trigger blade carried by the trigger lever, a spring which opposes the movement of the trigger lever in the pull-off sense, a sear, which cooperates with the trigger lever, and a catch lever, which in a catching position interlocks with the sear and is adapted to retain a spring-loaded striker, which serves to actuate the valve.

Abstract: A trigger mechanism, particularly for sports pistols, comprises a trigger lever, which carries a trigger blade and is biased by a spring having a variable initial stress and opposing the pull-off movement of the trigger lever. The mechanism also comprises a sear, which cooperates with the trigger lever, and a catch lever, which is adapted to retain the spring-loaded striker and to interlock with the sear in a catching position. The trigger lever is movable against the sear against the spring force.

Abstract: A sports pistol comprises a housing, which extends in a substantially prismatic recess formed in a grip and is held in that recess by means of a fixing screw that extends upwardly from the bottom of the grip. In order to permit an adaptation of the pistol to the attitude of the hand of a given shooter, the housing extending in the recess defines clearances with the side faces, the bottom surface and the rear surface of the recess and is supported on the bottom surface and on the rear surface of the recess by respective pairs of adjusting screws, which are disposed on opposite sides of the vertical longitudinal center plane of the housing. Besides, the fixing screw extends at an oblique angle to the bottom surface and at an oblique angle to the rear surface of the recess and is screwed into a member that is mounted in the housing for rotation on an axis which is normal to the vertical longitudinal center plane of the housing.
