Our Slide Completion Kits have become a cult favorite among gun mod enthusiasts for our tight tolerances and internals built to specifications that equal or exceed OEM components. For example, our firing pins, depressor plungers, and firing pin safeties are cut from solid 17-4 stainless steel, not MIM’d. Striker weight exactly matches Glock factory as does striker spring specification. Our polymer components are injection molded in house to tight tolerances. We also offer frame completion kits which include our Elite trigger. Frame Completion kits can be ordered for a standard frame or for a Polymer 80 frame (does not included locking block or P80 provided pins).
