  • Patent number: 6415539
    Abstract: The pistol comprises a frame. A trigger is mounted in the frame and is pivotable between a release position and a firing position. The frame comprises a trigger, guard for protecting the trigger. A safety lever is pivotally attached to the trigger guard and spring-urged into a safety position in which it locks the trigger in its release position. The safety lever is pivotable into a second position in which the trigger is free to be pivoted into its firing position.

  • Patent number: 6266909
    Abstract: A pistol includes a frame; a slide mounted on the frame for forward and rearward motions relative to the frame to assume a forward, basic position and a rearward, pulled-back position; a firing pin mounted in the slide for forward and rearward motions relative to the slide; a firing pin catch affixed to the firing pin and movable therewith as a rigid unit; a firing pin spring mounted in the slide and urging the firing pin in a forward direction; a trigger movably supported in the frame; a trigger rail coupled to the trigger for executing a triggering motion when the trigger is pulled; and a sear for operatively connecting the trigger rail with the firing pin catch such that during forward motion of the slide the sear arrests and holds the firing pin catch whereby the firing pin spring is armed and that upon pulling the trigger, the sear is moved away from the firing pin catch by the trigger rail for allowing the firing pin to accelerate forwardly as urged by the firing pin spring.

  • Patent number: 6263607
    Abstract: A pistol includes a frame; a slide reciprocating on the frame between a forward position and a pulled-back position; a firing pin mounted in the slide for motions relative to the slide; a firing pin catch affixed to the firing pin; a firing pin spring mounted in the slide and urging the firing pin forwardly; a trigger supported in the frame; a trigger rail coupled to the trigger for executing a triggering motion when the trigger is pulled; and a sear for connecting the trigger rail with the firing pin catch such that during forward motion of the slide the sear arrests and holds the firing pin catch thus arming the firing pin spring and that upon pulling the trigger, the sear is moved away from the firing pin catch by the trigger rail for allowing the firing pin to accelerate forwardly. A manually operable disassembly member which has an open and a closed position, is movable into a pulled-out state for allowing the slide to be taken off the frame.

  • Patent number: 6253479
    Abstract: The pistol comprises a frame. A trigger is mounted in the frame and is pivotable between a release position and a firing position and spring urged into the release position. The frame comprises a grip portion with a magazine well in which a magazine is removably inserted. A trigger bar is pivotally attached to the trigger and spring urged upwardly. The trigger bar has an abutment member at its rear end which coacts with a sear member that is movably mounted in the frame. A safety member is mounted on the grip portion and is movable between two positions. At its upper end the safety member has a catch for engaging the trigger bar. A second spring urges the safety member into its first position in which the catch pulls the trigger bar down out of engagement with the sear member. The safety member has an abutment face which is engaged by a part of the magazine when the latter is inserted. The part pushes the safety member into its second position in which the catch is out of engagement with the trigger bar.

  • Patent number: 6234059
    Abstract: A pistol includes a cross-sectionally U-shaped frame which has first and second opposite side walls, a formed-on grip, a formed-on trigger guard, a first through bore provided in the first side wall and a second through bore provided in the second side wall in alignment with the first through bore. A structural unit is removably accommodated in the frame above the trigger guard and includes bilateral guide rails and a through aperture aligned with the first and second through bores. The structural unit is received in the frame with a form fit for preventing longitudinal displacements of the structural unit relative to the frame. A removable pin passes through the first and second through bores and the through aperture in the structural unit for removably securing the structural unit to the frame. A slide is received in the frame for forward and rearward reciprocating motions relative to the frame. The rails of the structural unit cooperate with the slide for guiding the slide during its reciprocating motions.
