About Glock Upgrade Parts
Glock Upgrade Parts is an independent US store for lawful drop-in Glock triggers and small parts: connectors, trigger shoes and bars, springs, plungers, extractors, pins and magazines for Gen 3, Gen 4 and Gen 5.
We are not affiliated with Glock, Inc. Every part is listed by the generation it fits and what it changes, prices and stock are live when you order, and parts ship to your door; the pistols we list go to a licensed dealer near you. We also keep city guides for 20 cities, with who issues carry licenses, the hunting zone and the nearest public ranges.
How we work
- Online only. There's no showroom to visit. Everything is ordered here and picked up at your own FFL dealer.
- Live price and stock. What you see is checked again when you order.
- Every firearm through an FFL. We ship guns only to licensed dealers, who complete the background check with you.
- Straight answers. Ask us anything before you buy — about a model, a caliber, or how a transfer works.
What we don't sell
We don't sell NFA items (suppressors, short-barreled rifles or shotguns, machine guns), and we don't ship items to places where they're prohibited.
