ABSTRACT:
FIELD AND BACKGROUND OF THE INVENTION
A pistol comprising a frame, a pivotable trigger and a trigger guard for protecting the trigger is described in U.S. patent application Ser. No. 09/234,420 filed Jan. 20, 1999 and Ser. No. 09/255,725 filed Feb. 23, 1999 which are declared an integral part of the present patent application.
A further pistol with the above elements is described in European patent No. 77 790 and in U.S. Pat. No. 5,669,169.
SUMMARY OF THE INVENTION
It is an object of the present invention to increase the safety of such a pistol against accidental firing.
This object and others to become apparent as the specification progresses are accomplished by the invention according to which, briefly stated, 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 rail. A 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.
