Abstract
A safety catch for a self-loading pistol type fire arm is provided with a safety catch comprising an arbor (HH) rotatable in the fire arm frame (A) by means of manual levers (HH2 and JJ2) mounted outside the frame on either side. From a rest or off position, in which the fire arm can be fired, the arbor can be rotated upwardly to an end position in which means on the arbor engage the hammer (J) when it is in either the cocked or uncocked position, to lock it against rotation and thus prevent the pistol being fired. Additionally, when the hammer is cocked, the arbor can be rotated in the opposite direction, in which case it causes rotation of a detent member (LL) which lifts the ejector (L) to engage and hold the firing pin and to retract the end (S2) of the firing pin (S) struck by the hammer (J) within the slide (B) and thereafter to trip the sear (K) to release the hammer (J) safely from the cocked to the uncocked position.
