Shadow Systems Round Tip Firing Pin Assembly Features The Shadow Systems Round Tip Firing Pin Assembly is machined from 17-4 stainless steel a material selected for its strength and corrosion resistance under the repeated impact cycles a firing pin experiences. The round tip profile is standard weight and length matching the factory configuration used across compatible Shadow Systems pistols for reliable consistent primer strikes. A standard weight firing pin spring provides the tension needed to drive the pin forward with enough force for dependable ignition shot after shot. This kit is designed to fit Shadow Systems pistols exclusively ensuring correct dimensions and function without the fitting issues that can come from generic replacement parts. The complete assembly includes a spacer sleeve and two spring cups along with the firing pin return spring giving owners everything needed for a full factory-correct installation in one package. It s worth noting that rectangular tip firing pins use a black spacer sleeve while this round tip version uses a grey or green spacer sleeve helping technicians and owners identify the correct configuration at a glance. Replacing a worn or damaged firing pin assembly with factory-correct Shadow Systems components helps maintain the pistol s original reliability and ignition performance.
