The 3CR Tactical 9mm replacement barrel drops directly into any Gen 3 Glock 19 frame and slide assembly. Built from 4150 chrome moly vanadium steel and finished in a hard black nitride coating, this barrel delivers factory-grade fit with improved corrosion resistance and a tighter chamber for more consistent accuracy.
The black nitride treatment penetrates the steel surface for lasting wear resistance, so the barrel keeps its finish through high round counts without flaking or chipping. The chamber is cut to SAAMI 9mm Luger spec for safe use with all standard pressure factory ammunition.
Specifications:
A direct replacement requires no fitting on factory Gen 3 frames. Strip your slide, swap the barrel, reassemble, and function-test with snap caps before live fire. Confirm ejection and feeding with your carry ammunition before duty or competition use.
