Treatment with the gun safety is ensured by a fuse, blocking the firing pin from the impact of the hammer and the locking bolt and the trigger in the forward position. Safety during disassembly and assembly of the gun increases, the impossibility of removing the shutter from the frame without prior separation of the charged store.

for 30 plus years of production the pistol PSM not upgrade and modify,, except for the handle shell.A feature of PSM pistol is the location of the head guard flag over the rear part of the shutter. This provides the ability to simultaneously turn off the fuse and cocking the hammer by simultaneously pressing the thumb, holding a gun, or the palm of the other hand. When attaching the handle to the gun connection thread, requiring use when disassembling and assembling special tools, replaced by a stopper. This simplifies assembly and disassembly of the gun, and ensure reliable fastening of the handle to the gun. The handle is made of light alloy instead of plastic, which increased survivability and reliability of the pistol work in difficult conditions.
