Factory- and P80-compatible GLOCK® upper parts and springs.

You bought an upgraded slide for your P80 or GLOCK -- now you need to finish the assembly and install it. Simple, we have you covered. These upper parts kits are made for the most popular slides (Glock 43, G17, G19, and more), and they're guaranteed to work with any factory or aftermarket slide marketed for the GLOCK and Polymer80 handgun series or slides and frames.

GLOCK® Upper Parts Kit: What's Included?

Each GLOCK®/P80 UPK includes the following components:

  • Recoil Spring Assembly
  • Channel Liner
  • Extractor
  • Firing Pin
  • Spring Slide Cover Plate
  • Extractor
  • Depressor Plunger Spring

Pair With a Custom Slide and Barrel

Complete your custom P80 build - or upgrade your factory GLOCK - by pairing one of these upper parts kits with a custom slide and barrel. By building your own slide, you'll enjoy better performance. Grab a threaded barrel and throw on a compensator to improve accuracy and felt recoil. Invest in a high-quality LFA slide that's pre-cut for an optic like the RMR. You'll save money in the process compared to buying a "premium", off-the-shelf unit.
