FAQ
Is this a true drop-in barrel, or will it require fitting?
This is designed as a drop-in barrel for standard Glock 19 pistols. It should install directly into your OEM slide without modification, though we always recommend checking for proper function and headspace after installing any critical component.
Does the threaded barrel come with a thread protector?
Yes, a steel thread protector is included to shield the threads when a muzzle device is not attached. Ensure it is properly tightened and checked periodically during firing.
