SIG SAUER P225 9mm P6
The DPM USA’s recoil reduction system is a direct replacement for the stock guide rod and does not require modification on the firearm. The spring systems work due to the multi spring intricate rod (three spring system) and controls the function of the firearm. Included with the system are additional external springs, and some cases spacers, that way the shooter can fine-tune their firearms to match their personal standards. These springs produce such an advanced recoil reduction by slowing the slide down before impact with the frame on the firearm.
