FAQ
Is this a true drop-in barrel, or will it require fitting?
This barrel is manufactured to be a drop-in fit for most standard Glock 19 pistols. We always recommend checking for proper lock-up and function with your specific slide and ammunition after installation.
Will this barrel work with my aftermarket slide?
While compatible with OEM Glock slides, some aftermarket slides have tighter tolerances. It is your responsibility to verify compatibility with your specific slide model, as minor fitting may occasionally be required.
What thread protector or muzzle device do I need?
You will need a 1/2×28 thread protector or compatible muzzle device. Most common 9mm compensators and suppressors use this thread pattern. A thread protector is not included with this naked stainless steel barrel.
