True Precision Sig P320 Compact/X-Carry/M18 9mm Luger 3.90" Drop-In Barrel - Black Nitride

The True Precision TPP32CBXBL is a precision drop-in pistol barrel machined from stainless steel and finished in Black Nitride, engineered as a direct-fit replacement for the factory barrel in the Sig Sauer P320 Compact, P320 X-Carry, and P320 M18 pistols chambered in 9mm Luger.

This 3.90" barrel installs without gunsmithing - drop it in and you're done. It features a 1:10" RH twist rate optimized to stabilize a wide range of modern 9mm Luger defensive and target projectiles. The Black Nitride surface treatment enhances corrosion resistance, reduces friction against bullet jackets, and makes routine cleaning easier than a standard stainless bore. The barrel ships without sights, allowing continued use of the host pistol's existing sight system.

Manufactured by True Precision to tight tolerances, this aftermarket barrel is an excellent upgrade for P320-pattern shooters looking to refine accuracy, switch to a more durable finish, or replace a worn factory barrel on their compact-frame Sig pistol.
