Griffin Armament ATM Threaded Barrel for Sig Sauer P320C 9mm Luger Black Nitride

Overview

The Griffin Armament ATM (Advanced Threaded Match) Threaded Barrel is designed for the Sig Sauer P320C in 9mm Luger. Billet-machined from pre-hardened 416R chromium stainless steel, this 4-inch match barrel is manufactured using single-work-holding 5-axis machining to ensure precise dimensional consistency and an optimal geometrical relationship between the breech, slide, and locking lug. Featuring a durable black nitride finish that resists surface wear and corrosion while increasing surface hardness, the barrel includes a 1/2"-28 threaded muzzle with a target crown for suppressor or accessory support. The chamber is honed and polished for smooth, reliable function with a wide range of ammunition, from training rounds to duty loads. It also utilizes broach-cut rifling and a 1:10 twist rate, and comes complete with a loaded chamber indicator cut and a lightweight Micro Carry Compensator to reduce recoil and improve follow-up shot control.
