Glock 19 Gen 3/P80 PF940C – 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 19 and Polymer80 PF940C 9mm builds. It includes the core upper-slide internals needed for a new compact slide build or rebuild, including an upgraded striker and a stainless steel guide rod/spring instead of a factory-style plastic guide rod.
This kit is built for customers completing a compatible Glock 19 Gen 3 / PF940C slide setup. It is not a lower parts kit, not a trigger kit, and not a universal Glock parts bucket. Compact Glock fitment matters here—close enough is how builds start cussing back.

What it does
This kit supplies the internal upper-slide parts needed to complete or rebuild a compatible Gen 3 Glock 19 / PF940C 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 compact slide build lives or dies by 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.

Tools needed
Basic Glock slide assembly tools are recommended, including a proper channel liner tool, punch, non-marring bench block or work surface, and eye protection. Tiny spring-loaded parts love disappearing like they owe child support.
Install notes
Install carefully and 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 and test fire safely before trusting the build.
Verify before you buy
Verify your slide is a Gen 3 Glock 19 / PF940C-compatible 9mm slide before ordering. This is an upper slide parts kit only. If you are building the frame too, you will still need the correct lower/frame parts separately.
