The DPM recoil reduction system for the CZ P-10S replaces the factory recoil system. A multi-spring rod with 2 springs inside spreads the recoil, so the pistol moves less and you get back on target faster. It comes with 2 external springs of different power, so you can tune it to your ammunition. It is made in Greece.
The compatibility list covers the P-10S and P-10S OR. Systems for other CZ pistols are in Recoil reduction springs.
