True Precision Sig Sauer P320 3.9" 9MM Non-Threaded Barrel, Black Nitride

TRUE is proud to offer its drop-in ready barrel for the Sig Sauer P320 Compact, designed for the 3.9" P320 Compact, X-Carry & M18 9mm models (also available for P320 X Compact, 3.6”). TRUE barrels deliver unmatched accuracy, combining advanced cuts, chamfers, and feed ramp designed to outperform OEM standards and to ensure reliable feeding of all types of ammunition designs. Our proprietary stainless steel broach cut rifling underscores our commitment to those who demand only the best. The TRUE barrel stands as the definitive Sig P320 Compact upgrade - Experience American-made precision, performance, and style. 

Black Nitride, known as "Melonite," provides a deep, hardened, jet-black finish from within the steel, whereas PVD offers various colors with varying wear resistances, including the less durable TRUE Blue. TRUE Precision also features a customizable Satin Stainless finish, which is corrosion-resistant but benefits from regular maintenance.

Specifications

• New for 2023, all P320 models from True Precision will no longer have the LCI peep hole cut on top. This will assist in keeping pistol mounted optics clean and free from powder blowback and debris escaping from a LCI hole. Those with an LCI can remove the LCI from the slide to use this barrel.
• Fits the Sig P320 Compact, X-Carry, and M18 (will not fit the X-Compact). Easy to install drop-in design. May require some minor fitting when used on older variation X-Carry slides.
• No LCI cut on new production barrels. This is optimal when using slide mounted optics and prevents excessive fogging/powder blow-back on the glass. Can be used with the M18 when LCI removed/shortened.
• Barrel is 3.87" in overall length. 
• Advanced proprietary broach cut design specifically engineered for increased accuracy potential.
• Broach cut 6 groove rifling allows for all ammo types to be used safely, including cast lead.
