The Zaffiri Precision Threaded Barrel for Glock 19 (brand part no. BA-G19G15-TH-SS) is a drop-in match-grade barrel finished in stainless steel and built to fit Glock 19 pistols across Generations 1 through 5. Machined from 416R stainless steel that is stress-relieved and heat-treated, it is rifled with a 1:10 twist rate and finished with a polished feed ramp for smoother feeding across lead, plated, and jacketed bullets. Zaffiri Precision cuts a target crown at the muzzle and an oversized lockup area for a tighter, more consistent barrel-to-slide fit than a factory barrel. The threaded muzzle is cut 1/2×28 and ships with a thread protector, so it’s ready for a suppressor or muzzle device as soon as it’s installed.
