The DPM System is a direct replacement for the stock recoil rod and does not require any modification to the pistol. As always, DPM products are designed and developed with user’s safety as a priority. Exceptional manufacturing and engineering using high-end materials.

The US patented recoil reduction system works due to the multi spring intricate recoil rod (3 different energetic springs), controls the functionality of the pistol and replaces the stock recoil rod without recquiring any modification. The third spring which is contained within the recoil rod controls the movement of the slide so it never rams on the frame.
