Replacement barrels for Glock handguns are a popular customization option, allowing you to extend the life of your handgun after years of service. These 4.375" barrels are designed for the Glock 17, with a threaded muzzle. Stainless steel construction. Standard-cut rifling, 1:16 twist, also handles unjacketed ammunition better than factory hexagonal rifling; opening access to lead practice ammunition. The slightly longer length than a normal G17 barrel will produce a slightly higher muzzle velocity, and the threading provides a mounting point for a suppressor or muzzle brake.
