 Quality GLOCK® Parts for factory and custom-built P80 pistols.

Like the popular AR-type rifle, the GLOCK® handgun is loved for its massive market of aftermarket and custom parts. At 80% Lowers, we're happy to provide a catalogue of American-made, custom GLOCK® barrels, slides, and individual slide and frame parts to complete or upgrade your favorite striker-fired handgun.

P80 Frames and Parts Available

Starting your first "from-scratch" build? Check out the P80 frames.  Need all the other parts to finish your pistol? You're still in the right place! We have lower and upper parts kits, barrels, slides and more! - for GLOCK's most popular handgun series, including the G17, G19, and G43.

Drop-in GLOCK® Barrels and Slides

You built or bought a GLOCK, and now you wanna make it better. Easy. Check out some of our match-grade barrels, like this target-crowned GLOCK 17 barrel. It's compatible with factory and P80 Gen 3 pistols.

Optic-Cut GLOCK® Slides

Few upgrades are better than a micro-red dot, but you need the right optic-cut slide. We've got you covered with quality slides made from 416 stainless, provided by LFA. Their Elite G17 Slide is pre-machined for an aftermarket reflex sight, like the popular Trijicon RMR. Coupled with weight-reducing vents and a tough Cerakote finish, an upgraded slide like the LFA Series is a perfect way to set your GLOCK® or P80 pistol apart from all the rest.
