GLOCK GEN 4 20-21-40-41 & SF Models
The DPM Systems Glock recoil reduction system is a direct replacement for the stock guide rod and does not require modification to the firearm. The pistol recoil management spring system works due to the multi spring intricate rod (three spring system) and controls the function of the weapon. This top of the line recoil reducer system produces advanced recoil reduction by slowing down before impact with the frame of the firearm. Additional external springs are included, and in some cases spacers, so the shooter can fine-tune their firearms to match their personal needs. Therefore, this triple spring recoil reduction eliminates slamfire and malfunctions.
