Brownells Lower Parts Kit For Glock 17/19

The Brownells Lower Parts Kit for Glock 17/19 is a complete set of aftermarket frame components engineered to let you build or rebuild a full-size or compact Glock-platform handgun from the frame up. Whether you're assembling a pistol from a polymer 80 frame, completing a Glock frame, or refreshing internals on an existing gun, this kit contains all the small parts you need—springs, pins, catches, and housings—manufactured to exacting tolerances for reliable fit and function. It's the kind of kit that saves you from hunting down individual parts across multiple suppliers.

These are genuine Brownells aftermarket components, trusted by gunsmiths, custom builders, and DIY shooters who demand consistency and quality. If you're working on a Glock 17 (full-size) or Glock 19 (compact), this kit covers both frames with the correct dimensions and geometry. Assembly requires basic firearms knowledge and the right tools, but the payoff is a properly functioning pistol tailored exactly to your needs.

Brownells has been the go-to source for firearms parts and gunsmithing supplies for decades—and for good reason. Their frame kits are known for attention to detail and parts that work the first time, which matters when you're building something you rely on.
