SGM Tactical SGMTGB17TN: Aftermarket replacement barrel for 9mm Glock handguns. 4.375" length for the Glock 17.
1:16 Twist, Black Nitrite finish, threaded.
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. Protective black nitride finishes increase barrel life.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.
