Agency Arms 419 9mm Threaded Barrel for SIG Sauer P320 Compact – Black DLC Finish

The Agency Arms 419 threaded barrel transforms your SIG Sauer P320 Compact into a suppressor-ready platform without compromising reliability or accuracy. Machined from 416R stainless steel and finished with a durable black DLC (Diamond-Like Carbon) coating, this barrel provides the corrosion resistance and wear properties serious shooters demand when running suppressed or adding muzzle devices.

This barrel features 1/2x28 threading at the muzzle to accept standard 9mm suppressors and compensators. The single-port compensator design helps reduce muzzle rise during rapid strings of fire. Drop-in installation replaces the factory P320 Compact barrel with no gunsmithing required. The DLC finish matches OEM black slides and provides superior hardness and lubricity compared to traditional Nitride or Melonite treatments.
