Brownells Slide Parts Kit With Billet Firing Pin, Glock 19 Gen3

Building or refreshing a Glock 19 Gen3 slide? The Brownells Slide Parts Kit with Billet Firing Pin gives you everything you need in one complete package. Whether you're assembling an aftermarket slide from scratch or bringing a factory slide back to factory-fresh condition, this kit supplies all the internal components—and the critical billet firing pin—to get the job done right.

The kit's standout upgrade is the billet firing pin, engineered for superior strength compared to standard alternatives. The extractor is cast from 17-4 stainless steel, and other wear-critical components—the extractor depressor plunger and firing pin safety—are precision-machined from bar stock for consistent fit and function. All parts are manufactured to factory specifications, so they integrate smoothly into a factory-spec slide without fitment guesswork.

Brownells includes the channel liner tool, so you can properly install the channel liner yourself without improvising. This attention to detail—and the inclusion of a specialized installation tool—separates a kit built for builders from a basic parts dump. If you're deep into Glock customization or simply want to replace worn internals with quality components, this is your go-to Glock 19 Gen3 slide kit.
