Zaffiri Precision Zp.43Btbn 9Mm G43/43X 3.92" Black 416R S/S

The Zaffiri Precision Zp.43Btbn is a match-grade replacement barrel engineered for shooters who want tighter groups and reliable performance from their Glock 43 or 43X. Built from 416R stainless steel and manufactured in the USA, this drop-in barrel swap delivers the precision and durability serious pistol shooters expect—without compromise on accuracy or longevity. Whether you're a competition shooter refining your setup, a defensive carrier upgrading for reliability, or a range enthusiast chasing tighter groups, a quality aftermarket barrel is one of the highest-impact upgrades you can make to any pistol.

This Zaffiri barrel comes threaded at 1/2 x 28 muzzle with a thread protector included, though you should verify that threaded barrels are legal in your jurisdiction before purchasing. The 3.92-inch length maintains the compact profile of the 43/43X platform while the 416R construction—stress relieved and heat treated to RC 40-42—ensures consistent performance across thousands of rounds. The oversized lockup area and fully supported chamber work together to maximize reliability with all bullet types: lead, plated, and jacketed. Conventional rifling paired with a polished chamber and bore keeps feeding smooth and reduces the buildup that slows you down at the range.

Setup is straightforward—this is a true drop-in design, so installation takes minutes and requires no gunsmithing. The target crown and improved feed ramp geometry contribute to both accuracy and function, and the large ZP logo machined into the lockup identifies your upgrade at a glance. A genuine match-grade barrel represents a real performance step forward for anyone serious about their Glock's potential.
