The Zaffiri Precision Glock 19 threaded barrel is a 9mm replacement barrel machined from 416R stainless steel and finished in gold TiN (brand part no. BA-G19G15-TH-GLD). It is built for the Glock 19 across Gen 1 to Gen 5, and its 1/2×28 threaded muzzle takes a compensator, a thread protector or a suppressor mount. The barrel is heat treated to RC 41, with a polished feed ramp, a target crown and an oversized lock-up area for consistent fit. It suits a shooter who wants a threaded Glock 19 barrel that is made in the USA and handles lead, plated and jacketed ammunition.
