Shown in a toggle action recoil operated semiautomatic pistol is a safety shoe interposed between the sear and a rotatable shaft controlled by a lever mounted on the outside of the gun frame. The sear is channel shaped with side walls extending rearward, its transverse leading edge being releaseably engaged with the hammer when the gun is cocked. The sear and the safety shoe are pivotally mounted on the same pin with the safety shoe positioned between the side walls of the sear. A projection on the leading edge of the safety shoe in loose fit engagement in a slot in the sear retains the safety shoe in loose fit engagement in a slot in the sear retains the safety shoe at right angles to the hammer engaging edge of the sear. Limited rotation of the shaft will cause the safety shoe to be wedged between it and the sear, preventing its disengagement from the hammer.
