SAVE MONEY ON AMMO! Reduce Recoil!
Easily convert your .40 Caliber Glock to shoot 9mm 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 .40 caliber barrel on the outside chambered in 9mm … brilliant!
Swapping out recoil guide rods, ejectors, extractors, or strikers is not necessary.
Please note: Will work in Gen 1, 2, 3 and 4 Glock handguns. Threaded Conversion Barrels will NOT work with most compensators.
