U.S.-made handgun parts for GLOCK, Polymer80 and 1911.
Building a custom GLOCK-compatible P80 handgun or 1911 from scratch? Want to upgrade your factory pistol with some high-performance components? You're in the right place: We have a quality selection of US-made parts, barrels, slides, internals, and accessories for those platforms. Whether you need a threaded barrel, ported and optic-cut slide, parts kit, or an upgraded trigger, we have you covered.
Building a P80-framed hand? Grab a GLOCK-compatible parts kit to to finish your build after fabricating your frame. Take the opportunity to upgrade with a custom slide and barrel, too! We've sourced a quality selection of GLOCK slides that include unique coatings, RMR cuts for a micro red dot, and lightweight designs.
Custom 1911s can fetch premium prices. But if you want to own a custom .45 or 9mm, you don't have to pay those high prices. Fabricating your 1911 from an aluminum 80% frame means you get to cherry-pick the upgraded parts you want to finish your build. Pair your frame with the Stealth Arms 1911 Jig to start fabricating. Once fabricated, you can install your upgraded 1911 barrel, slide, and parts kit.
