If you're running a Sig Sauer P320 Compact, Carry, or X-Carry and want to add a suppressor or other muzzle device, this OEM Sig Sauer P320 Compact 9mm threaded barrel gives you the platform to do it. At 4.6 inches long with a 1/2-inch-28 thread pitch, this factory barrel swaps directly into your slide—no fitting required—and maintains full compatibility with the loaded chamber indicator your pistol was designed with. Sig Sauer factory barrels are heat-treated for the durability serious shooters expect, and you get a thread protector in the box to keep the muzzle threads clean when you're not running a can or brake.
This is a straightforward upgrade path for owners who already love their P320 platform but want suppressor-ready capability. Whether you're building out a home-defense or range gun with a can, or just want the versatility of threaded threads, this barrel handles it. The nitron finish resists corrosion, and the engineering is pure Sig—no surprises, no guessing on fit.
It's worth noting: this barrel works with any P320 originally designed to accept a 3.9-inch non-threaded barrel, so compatibility is broad across the Compact/Carry/X-Carry family. Drop it in, thread on your muzzle device, and get to work.
