Sig Sauer P365 3.1" 9mm Luger Carbon Steel Matte Barrel$164.38
Availability: In Stock
A quality factory replacement barrel is fundamental to keeping your Sig Sauer P365 or P365X running reliably. This Sig Sauer P365 9mm replacement barrel is the genuine OEM part (Model 8900776) engineered and tested by the manufacturer to exacting standards. At 3.1 inches, it matches the compact profile of these popular carry pistols while delivering the performance Sig is known for. The Gold Titanium-Nitride finish isn't just for looks—it provides a hardened surface that resists corrosion and improves lubricity, meaning easier cleaning and longer service life between maintenance cycles.
Whether you're replacing a worn barrel, maintaining a backup gun, or setting up a dedicated training rig, this is the part that belongs in your P365 or P365X. It's loaded chamber indicator (LCI) equipped, so you get the same functionality as your factory barrel. The Gold finish gives your pistol a distinctive appearance while the engineered metallurgy handles full power 9mm loads without compromise. This is a non-threaded barrel, so it won't accept suppressors or muzzle devices, but it's built to the same rigorous standards as the barrel that came from the factory.
Sig Sauer replacement barrels are a smart choice when reliability matters. Buy once, install once, and keep your carry gun or competition pistol ready.

This barrel is designed for the Sig Sauer P365, P365X, and P365-XMACRO models. It is compatible with both ported and non-ported P365 SAS variants, though if you install it in a ported slide, you won't get the recoil management benefits of a ported barrel design.
Yes, the barrel is fully compatible with ported P365 SAS slides. However, since this is a non-ported barrel, the slide's ports won't function as designed, and you'll lose the velocity and recoil reduction benefits of the ported system.
No, this is a non-threaded barrel. If you need suppressor compatibility, you'll need to select a threaded model.
Yes, this replacement barrel includes the loaded chamber indicator (LCI) feature, matching the safety and usability of your factory barrel.
