Zaffiri Precision IBS Ported Barrel for Glock 19 Gen 5 9mm Stainless

Gen 5 Glock 19 owners get their own version of the IBS barrel because the Gen 5 slide and barrel geometry will not accept the earlier part. Integrated Blowhole System refers to the single large port on top of the barrel, which sends gas up through the slide cutout instead of leaving it to lift the muzzle.

One big port beats several small ones for keeping carbon out of the way, and the shooter feels the difference as a flatter pistol on a fast string. The finish here is polished stainless. As with the rest of the IBS line, the barrel is built around a matching Zaffiri Precision IBS ported slide, so a stock Gen 5 slide is not the right host for it.
