This slide is precision-machined to the critical dimensions of an OEM Glock 17 Gen3 slide, ensuring reliable function with aftermarket frames. The use of 17-4 stainless steel, heat-treated and nitride-finished, provides superior corrosion resistance and surface hardness over standard carbon steel. Builders must source a separate barrel, recoil spring, and upper parts kit to complete their assembly. This is a component for building a custom firearm.
