Sig Sauer P365Xl 3.7'' Bbl 9Mm W/Lci Non-Threaded Gold

The Sig Sauer P365XL 3.7" barrel is a factory-OEM replacement part for shooters who need a direct swap for their compact 9mm pistol. Whether you're maintaining a duty or carry gun, upgrading a worn barrel, or building a backup upper assembly, this non-threaded barrel delivers the reliability Sig Sauer's micro-compact platform is known for. The gold titanium nitride finish resists corrosion and provides a durable, professional appearance that stands apart from standard black nitron variants.

This is a precision-engineered OEM component, not an aftermarket alternative. It features Sig's factory loaded chamber indicator (LCI) witness hole, so you get the same proven functionality as your original barrel. The 3.7-inch length is the standard P365XL specification, giving you the full sight radius and velocity potential the platform was designed around. The non-threaded design means it won't accept suppressors or muzzle devices—this is the classic configuration Sig built the platform on.

If you shoot a P365XL and need a replacement barrel or are building a spare complete upper, this is a no-guessing-games part. Drop it in, verify proper fit, and you're done. Shooters who run tight round counts, practice hard, or simply want a spare component on hand will appreciate having an OEM barrel in the safe.
