Operation
The P22 with a GEMTECH suppressor

The P22 may be fired double action at about 11 pounds of force, and operates as a single action with slightly more than 4 pounds of force.[1] The P22 operates by blowback where pressure generated by a firing cartridge is countered by a combination of the inertial weight of the slide assembly and the force of the recoil spring. The action will not open until the projectile has left the barrel and the pressures have dropped to safe levels. The gun will not cycle efficiently unless high velocity .22 rounds are used.
