This DPM Mechanical Recoil system  is special made for Glock 20-21 Gen 5, offers adjustablility to the user, it is easy to install on the frame and assemble the slide with the frame. 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.

This kit includes 4 different in length and strengh external springs and 2 self-lock spring plugs, for the 2 gold coated springs their wire diameter is 1.15mm and are lighter during the slide travel than the 2 silver coated springs with wire diameter 1.2mm.
