True Precision Sig P320 X-Compact 9mm Luger 3.6" Threaded Gold TiN Stainless Drop-In Barrel

Upgrade your Sig P320 X-Compact with this True Precision threaded drop-in barrel chambered in 9mm Luger. Purpose-built as a direct replacement for the factory 3.6" P320 X-Compact slide, this aftermarket barrel brings precision-machined construction, a threaded muzzle for compensator or suppressor use, and a standout Gold TiN finish.

Machined from 416R stainless steel and cut with True Precision's proprietary broach-cut, 6-groove rifling at a 1:10 RH twist, this barrel supports the bore geometry needed for match-grade accuracy in duty, range, and competition use. A 1/2x28 thread pitch at the muzzle allows the same 9mm muzzle devices used across the broader Sig P320 ecosystem to mount directly. The threaded barrel measures 4.30" overall, fitting as a drop-in part into a standard 3.6" P320 X-Compact slide without the need for fitting.

Designed specifically for the Sig P320 X-Compact (3.6"), this threaded barrel adds muzzle-device versatility to one of Sig Sauer's most popular carry and duty platforms. The Gold TiN (Titanium Nitride) coating offers strong wear and corrosion resistance while giving the slide a coordinated custom look. Whether the goal is reduced recoil with a comp, hearing protection with a 9mm suppressor, or swapping a worn factory barrel for a more accurate replacement, this drop-in barrel delivers a clean, no-fitment-required upgrade.
