I have been informed that the PPQsc uses the same recoil spring as the PPS and PPSm2, but that the P99c uses a heavier spring, can anyone confirm this? If it’s true, what would the reasoning behind that be? The felt recoil on the PPQsc, from my testing, is noticeably more than the PPS, after this research I would assume that’s because of the extra weight and mass of the slide while using the same spring. Does anyone have both a P99c and a PPQsc to compare recoil assemblies? Any information on this subject would be extremely helpful.
