FAQ
Is this a true drop-in barrel, or does it require gunsmith fitting?
This Combat Armory barrel is engineered as a drop-in fit for the Glock 19. It should install into your slide without modification, but as with any aftermarket part, function testing is always recommended.
Does it come with a thread protector?
