Glock 17 Gen 3/P80 PF940V2 – Upper Slide Parts Kit – Stainless Guide Rod
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Cross Armory Standard Upper Slide Parts Kit is a slide completion kit for Gen 3 Glock 17 and Polymer80 PF940V2 9mm builds. It includes the core upper-slide internals needed to complete a compatible slide, including an upgraded striker and stainless steel guide rod/spring instead of a factory-style plastic guide rod.
This kit is built for compatible Glock 17 Gen 3 / PF940V2 upper slide work only. It is not a lower parts kit, not a trigger kit, and not a universal Glock parts dump. Pick the right kit or the build starts fighting back.

What it does
This kit supplies the internal upper-slide parts needed to complete or rebuild a compatible Gen 3 Glock 17 / PF940V2 slide. The included stainless steel guide rod/spring gives the build a stronger guide rod setup than a basic plastic guide rod system.
Why it’s worth it
A slide build is only as good as the small parts inside it. This kit gives builders a clean upper-parts package from Cross Armory with the striker assembly parts, extractor system parts, safety plunger parts, channel liner, backplate, and guide rod/spring needed to finish the top end correctly.
The big value here is keeping the upper build organized. Instead of chasing individual parts one at a time and hoping nothing gets missed, this kit gives the slide the core internals it needs in one package. Less chaos. Fewer mystery failures. More time actually building the gun instead of hunting tiny parts across the bench like a raccoon with a flashlight.

Install notes
- Install only on an unloaded firearm or unfinished slide assembly.
- Verify extractor function, striker movement, safety plunger movement, backplate retention, guide rod seating, and slide cycling before live fire.
- After assembly, perform a full function check before test firing.
- If you are not comfortable completing a slide assembly, use a qualified armorer or gunsmith.
Verify before you buy
- Verify your slide is a Gen 3 Glock 17 / PF940V2-compatible 9mm slide before ordering.
- Verify you are buying an upper slide parts kit, not a lower/frame completion kit.
- Verify your slide, barrel, recoil system, extractor setup, and backplate configuration are compatible.
- If you are building the frame too, you will still need the correct lower/frame parts separately.
