Zaffiri Precision IBS Ported Barrel Glock 43X 9mm

A 43X is a small gun firing a full power cartridge, which is exactly where porting earns its keep. Zaffiri Precision machines chunk ports into the top of this barrel so they line up with the cuts in their IBS slide, bleeding gas upward as the bullet clears and letting the front sight settle faster between shots.

The catch is fitment. These ports index with the Zaffiri Precision IBS ported Glock 43/43X slide only, not a factory slide and not another maker's cut, so build the upper around a matching pair. The barrel is stainless steel under a black nitride finish that hides holster wear, and the muzzle is not threaded. Chambered in 9mm.
