These are not standard 1911 aftermarket hammer springs which are longer than the gsg springs. These are designed specifically for the GSG/SIG 1911-22
The "FirstStrike" Firing Pin is designed to minimize light hits on the GSG and SIG 1911-22. It's precision Wire EDM machined from S7 tool steel. The impact section of the firing pin is then surface ground to create the optimal “FirstStrike”. The firing pins are heat treated to a Rc of 55 to prevent any excessive wear and deformation that can be found on the factory stamped firing pin.
