(That release button is also used to field strip the pistol. This button is mounted on the frame, near the rear of the slide, on the left side.
The grip safety stays in the depressed condition until a ‘release’ button is pressed. Unlike the grip safety on pistols made by Colt and other manufacturers, the safety does is not spring-loaded and does not automatically extend when not manually depressed. When depressed – safety disengaged – the firearm is free to fire when the trigger is pulled.
When extended – safety engaged – the sear is blocked mechanically by some extension of the safety. Grip safety depressed, safety disengaged.
