Zaffiri Precision Glock 17 Gen 1-4 4.37" Flush and Crown Barrel

Zaffiri cuts this barrel to finish flush with the end of a Glock 17 slide, with the crown turned inward at the muzzle so nothing protrudes and nothing gets dinged. The blank is stainless steel with a black finish over it, and the chamber and rifling are held to match tolerances, which is the entire reason anyone replaces a barrel that already works.

Installation is a slide strip and reassembly. No fitting, no gunsmith, no permanent change to the pistol, and the original barrel goes back in whenever you want it to. What you get in exchange is tighter lockup and a barrel that will hold a group better than a standard one, which matters if you shoot for score, load your own ammunition, or simply want the gun to shoot as well as it looks.
