Brownells Slide Parts Kit With Billet Firing Pin, Glock 19 Gen5

The Brownells Slide Parts Kit With Billet Firing Pin is a complete solution for gunsmiths, builders, and serious shooters who are refurbishing a Glock 19 Gen5 or assembling an aftermarket slide from scratch. Whether you're doing a resto on a worn factory slide or finishing a custom build, this kit delivers all the internal components you need to get your pistol back to factory-spec performance—minus the guesswork and the trips to three different suppliers.

What sets this kit apart is the billet firing pin, a significant upgrade from cast alternatives. The firing pin is machined from solid bar stock for added strength and reliability, while the extractor is cast from 17-4 stainless steel—materials chosen for durability under repeated cycling. The extractor depressor plunger and firing pin safety are also machined from bar stock, ensuring tight tolerances and consistent function. All parts are engineered to factory dimensions so they'll drop in and work without fitting or modification.

The kit ships complete with a channel liner tool, so you have everything required to properly install the channel liner and complete the job right. This is the kind of detail that separates a professional rebuild from a headache—having the right tool included saves time and eliminates improvisation on a critical component.

Brownells' reputation for accuracy and attention to detail shows in every component. If you're rebuilding slides regularly or working on a single high-quality project, this kit removes the friction from sourcing individual parts and lets you focus on getting your Glock 19 Gen5 running like it should.
