Makarov pistol
The PM has a free-floating triangular firing pin, with no firing pin spring or firing pin block. This theoretically allows the possibility of accidental firing if the pistol is dropped on its muzzle. Designer Nikolay Makarov thought the firing pin of insufficient mass to constitute a major danger. The Makarov pistol is notable for the safety elements of its design, with a safety lever that simultaneously decocks and blocks the hammer from contacting the firing pin and returns the weapon to the long-trigger-pull mode of double action when that safety is engaged. When handled properly, the Makarov pistol has excellent security against accidental discharge caused by inadvertent pressure on the trigger, e.g., in carrying the weapon in dense brush or re-holstering it. However, the heavy trigger weight in double-action mode decreases first-shot accuracy. The Bulgarian-model Makarov pistol was approved for sale in the US state of California, having passed a state-mandated drop-safety test though the certification was not renewed and it has since been removed from the roster of approved handguns.
