The Backup Tactical Sig Sauer P320 Full-Size 9mm Threaded Barrel in Flat Dark Earth is a purpose-built drop-in upgrade for standard P320 full-size pistols. Machined from 416 stainless steel and finished in a distinctive FDE tone, this 5.45-inch barrel adds 1/2x28 muzzle threads for easy attachment of common 9mm suppressors or muzzle devices while maintaining reliable factory-style fit.

This threaded barrel uses pulled-broach rifling with a 1:16 twist rate, optimized for a wide range of 9mm Luger loads. It is cut for a loaded chamber indicator and is listed to function in P320 full-size configurations with or without an LCI. Ideal for range use, training, and suppressed shooting setups, it offers a straightforward way to enhance accuracy and versatility without permanent modification. Backup Tactical’s attention to detail and consistent machining deliver a clean, precise upgrade that complements the brand’s reputation for quality pistol barrels.
