One Glock, Two Calibers!

Easily convert your .45 Caliber Glock to shoot 10mm in seconds!

Designed to allow shooters to change calibers by simply dropping in the Double Diamond conversion barrels in conjunction with the appropriate caliber magazine. The barrel is cut to fit in the ejection port of the intended slide. Basically, it's a .45 caliber barrel on the outside chambered in 10mm ... brilliant!

Swapping out recoil guide rods, ejectors, extractors, or strikers is not necessary.

Fits Gen1-4 models.

Double Diamond match grade replacement barrels are manufactured in the USA from the highest grade 416R stainless steel forgings. CNC machined and heat treated, providing a life time of service and better-than-factory accuracy at an affordable price.

The standard groove and land rifling make this an excellent choice for those who wish to shoot lead, plated, or jacketed bullets. Can be used in "C" model (compensated) Glocks, in addition to standard Glocks.
