Recoil Reducing Springs? DPM Systems in a Walther PPS
This video reviews the DPM Systems tunable recoil reducing operating spring and guide rod system for the Walther PPS. The system aims to progressively decelerate the slide, prevent frame slamming, and accelerate forward slide movement, resulting in reduced recoil and muzzle flip. Testing with two DPM springs (silver and bronze) and the factory spring indicated the silver spring offered a slight improvement in getting back on target quicker, though it was perceived as too stiff in some instances. The bronze spring was deemed too stiff overall. The reviewer suggests that with more break-in, the silver spring could be beneficial for competition shooters seeking a tenth-of-a-second advantage but noted it did not resolve issues with low-velocity rounds in the short-barreled pistol.
