Our goof is your gain! Save on ammo and your upgrade with our Blemished Double Diamond G20 Barrels!

A batch of these barrels were incorrectly stamped as .40 - 10mm. All blemishes are purely aesthetic and in no way affect performance! Order quickly, once this batch is gone, they're GONE! Please note that these barrels are only designed to fit Glock 20's, and only accept .40 S&W ammo.

Designed to allow shooters to change calibers by simply dropping in one of these conversion barrels; in conjunction with the appropriate caliber magazine. The barrel is cut to fit in the ejection port of the intended slide. Swapping out recoil guide rods, ejectors, extractors, or strikers is not necessary.

Please note: Not compatible with Gen 5 Glocks
