Glock 17 Firing Pins And Internal Parts

The small internal parts inside your slide do a lot of work for reliability. Our billet firing pin is milled from a single block of steel rather than stamped from powdered metal like most factory pins, which holds up better over time and lowers the risk of a light strike. It fits Glock 17, 19, and 26 platforms, so owners of multiple models can stock one part. 

Pair it with fresh spring cups and a spring-loaded bearing for a smoother cycle. These upgrades are cheap compared to the rest of a build, but they're often the difference between a gun that runs clean and one that jams.

Lower Parts Kits For Gen 1-3 Frames

If your trigger feels gritty or parts are worn, a full lower parts kit solves it in one order. Our lower parts kit from SCT manufacturing is built for Glock 17 and 19 Gen 1-3 frames with upgraded internals that outperform factory parts. It's a straightforward way to refresh your whole trigger group without hunting down each piece separately. A lower parts kit typically covers:

  • Trigger housing and connector
  • Slide lock and slide lock spring
  • Locking block and trigger pin
  • Magazine catch and spring

Replacing these as a set gives you a consistent trigger feel instead of mixing old and new components. Worn or mismatched parts can cause a mushy or uneven pull, and swapping them all at once fixes that in one step. It's an easy upgrade that makes a noticeable difference every time you shoot.

Complete Slide Parts Kits

For a fast finish, a complete slide parts kit puts everything in one box. Our Havatek premium kit for Glock 17 Gen 1-3 includes the billet firing pin, spring cups, an OEM recoil spring assembly, spring-loaded bearing, and slide cover plate. It's a smart pick if you just bought a stripped slide and need internals, or if you're refreshing an older slide.

Choosing Between A Full Slide Or Individual Parts

Not everyone wants to build piece by piece, and that's fine. If you'd rather skip assembly, we also carry complete slide assemblies that install straight onto your frame. Building from individual parts gives you more control over finish and internals instead. Think about your goal first:

  • Want the fastest setup? Go with a complete slide assembly.
  • Want full control? Build from a stripped slide and parts kit.
  • Happy with your slide but want better performance? Start with a barrel or firing pin swap.

Either path gets you a Glock 17 that fits how you shoot, whether that's at the range, in competition, or for daily protection. If you need help configuring your Glock 17 build, just reach out to our team!
