The DPM System’s FN Herstal FNP & FNX 4.5” Barrel recoil reduction system is a direct replacement for the stock guide rod and does not require any modification to the firearm. This top of the line recoil reducer system works due to the multi spring intricate rod (three spring system) and controls the functionality of the gun. This simplicit triple spring reduction 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 wants and needs. Therefore, the pistol recoil management system prevents any slamfire and gun malfunctions to happen while being used.
