True Precision TPP32CBXT SIG P320 Compact/X-Carry/M18 9mm Luger 3.90" Threaded Barrel - Satin Stainless

The True Precision TPP32CBXT is a drop-in threaded barrel purpose-built for the Sig Sauer P320 Compact, P320 X-Carry, and P320 M18 9mm pistols. Machined from 416R stainless steel with a smooth satin stainless finish, this 3.90" barrel installs as a direct replacement for the factory barrel to deliver tighter bore tolerances, improved accuracy, and a threaded muzzle ready to accept a compensator or sound suppressor. Each barrel is cut with a 1:10 RH rifling twist that safely handles all 9mm Luger ammunition, including cast lead loads.

Designed as a true drop-in part, the TPP32CBXT requires no fitting and mates with the factory slide and recoil spring assembly of the host Sig P320 Compact, X-Carry, and M18 platforms. The barrel ships ready to install with no sights included, so the host pistol's existing front sight profile is retained. Whether you are tightening groups on a duty or carry pistol or adding suppressor and compensator capability to the platform, this threaded barrel is a straightforward performance enhancement for the Sig P320 series.
