Brownells Pistol Barrel For Sig P365, 9mm, Thread, Black Nitride$114.31
Availability: In Stock
If you're building or upgrading a Sig P365, the Strike Industries P365 9mm barrel delivers precision engineering and genuine performance improvements in a drop-in package. This 3.10" fluted barrel combines 416R stainless steel with a black nitride finish to give you a durable, corrosion-resistant upgrade that's noticeably smoother and faster to maintain than factory steel. The fluting reduces weight while enhancing heat dissipation—practical benefits for shooters who put rounds downrange regularly. Whether you're customizing a carry pistol or assembling a new build from the ground up, this barrel installs directly into your P365 without gunsmithing.
The reverse target crown is purpose-built to shield the rifling at the muzzle, protecting one of the most vulnerable parts of the barrel from damage during handling, cleaning, or holstering. That small feature pays dividends over the life of the gun. The black nitride coating isn't just cosmetic—it's a genuine surface treatment that resists wear, corrosion, and the wear patterns that slow cleaning cycles. The barrel comes SAAMI spec chambered and ready to function as a proper drop-in replacement, so there's no fitting or headspace guesswork.
Strike Industries manufactures this barrel in the USA, and it pairs seamlessly with other SI P365 parts if you're planning a full custom build. One barrel ships with each order.

Yes. This is a direct drop-in replacement barrel designed for the Sig Sauer P365 with a 3.10" barrel. It installs without modifications or gunsmithing.
Fluting reduces the barrel's weight and increases its surface area, which helps dissipate heat during shooting. This is especially useful if you're running high round counts or testing loads at the range.
The reverse crown protects the rifling at the muzzle end of the barrel—a spot that's vulnerable to damage from holstering, cleaning, or accidental contact. This design shields the crown and helps preserve accuracy over time.
