Strike Industries P365 9mm Luger 3.10" Fluted Black Nitride Replacement Barrel - Fits Sig P365

The Strike Industries P365 Replacement Barrel is a precision-engineered drop-in upgrade for the Sig Sauer P365 micro-compact pistol. Machined from 416R stainless steel and finished in a durable Black Nitride coating, this replacement barrel delivers a high-performance package designed for direct installation without gunsmithing.

At 3.10" long and chambered in 9mm Luger, this drop-in barrel matches the standard factory P365 dimensions for direct, no-fitting installation. Fluting along the exterior reduces overall weight and increases surface area for faster cooling between strings of fire. A 1:10 twist rate with 6-groove rifling stabilizes a wide range of bullet weights, and a reverse target crown protects the rifling at the muzzle for consistent accuracy over the life of the barrel.

Weighing just 2.1 oz with a 0.53" barrel diameter, this Strike Industries barrel is a true drop-in replacement. Whether you're refreshing a heavily used carry pistol, replacing a worn factory barrel, or building out a P365 for dedicated range duty, this is a straightforward, high-quality upgrade backed by Strike Industries' reputation for innovative pistol accessories.
