Buy Glock Barrels Online

A match-grade barrel is the highest-value upgrade you can make to a Glock, and American Guns & Ammo ships hundreds of them nationwide. Our Glock barrel selection covers the Glock 17, 19, 19 Gen 5, 20, 21, 22, 23, 26, 34, 43 and more, in standard and threaded profiles.

Standard vs threaded

Standard barrels keep factory length and holster fit. Threaded barrels (1/2x28 on 9mm) add the option of a suppressor or compensator — and a thread protector keeps the muzzle clean until you mount one. If a can is anywhere in your future, buy threaded now.

Why conventional rifling matters

Factory Glock barrels use polygonal rifling and Glock advises against bare lead bullets in them. The match barrels we carry use conventional land-and-groove rifling with a polished bore, so they run lead, plated, coated and jacketed bullets alike — a real advantage for high-volume and reloading shooters. For the full decision walk-through, read our Glock barrel buyer's guide.
