Brownells Slide Parts Kit With Billet Firing Pin, Glock 17 Gen3

Building or rebuilding a Glock 17 Gen3 slide requires precision parts that fit factory specifications the first time. The Brownells Slide Parts Kit with Billet Firing Pin gives you everything needed to complete an aftermarket slide build or restore a factory slide to like-new condition. Whether you're a competitive shooter refreshing worn components or a gunsmith tackling a customer project, this kit consolidates the small parts that often get lost or sourced piecemeal from multiple vendors.

The kit emphasizes durability where it counts: the firing pin is machined from billet stock rather than cast material, delivering greater strength under repeated striker impacts. The extractor is cast from 17-4 stainless steel, a proven material for the cyclic demands of centerfire pistol operation. The extractor depressor plunger and firing pin safety are machined from bar stock to exacting tolerances. Every component is manufactured to match factory dimensions, so assembly into a spec-correct slide happens without fitting, filing, or guesswork.

Beyond the internal parts, Brownells includes the channel liner tool—a small but essential item that ensures proper installation of the channel liner without damage. That alone saves a frustration trip sourcing the correct installation method. Everything comes together as a complete system: springs, cups, spacer sleeve, slide cover plate, and guide rod assembly with recoil spring.
