Your Questions Answered
Will this slide fit a Gen4 or Gen5 Glock frame?
This slide is designed for Gen3-spec frames. Our staff notes it can fit on a Gen4 frame, but the fit may be slightly tighter compared to a Gen5. For optimal function, we recommend using it with Gen3 or Gen3-compatible frames like the Polymer80 PF940C.
Is the barrel included and is it threaded?
Yes. This is a complete slide assembly. It includes a gold-colored barrel that is threaded 1/2×28, which is the standard thread pitch for many common muzzle devices like compensators or suppressors (with proper tax stamp).
What is needed to complete the build?
You will need a compatible lower parts kit (LPK) and a Gen3-spec frame, such as a Polymer80 PF940C. The slide assembly includes everything for the upper: slide, barrel, recoil spring assembly, and all internal slide components.
