SIG SAUER P365-XL COMP .380 ACP Pistol

Description

SIG SAUER P365-XL COMP .380 ACP

The SIG SAUER P365-XL COMP brings integrated compensation and an XL-length grip to the P365 .380 platform. This exact black, non-manual-safety configuration is manufacturer part number 365XL380COMP with UPC 798681740321. It uses a 3.1-inch barrel, a striker-fired action and two included 12-round steel magazines, providing a listed capacity of 12+1 when loaded and when that capacity is permitted.

Integrated Two-Port Expansion Chamber

A two-port expansion chamber is built into the slide to redirect propellant gas and help reduce muzzle movement and perceived recoil. The compensated system does not require a separate threaded muzzle device or extend the pistol beyond its published 6.6-inch overall length. Its effect can vary with ammunition and grip technique, so owners should evaluate the pistol using the specific practice and defensive loads they intend to carry.

The 3.1-inch carbon-steel barrel has a black finish. The stainless-steel slide receives SIG SAUER’s Nitron finish and incorporates enhanced front and rear serrations. The slide is cut for the SIG-LOC Compact optic footprint. No electro-optic is listed as included with this package; an optic must be selected, mounted and zeroed separately using compatible hardware and the manufacturer’s specified torque procedure.

XSeries Ergonomics

The black XSeries modular polymer grip module extends the gripping surface compared with shorter P365 configurations and accepts the supplied 12-round magazines. Texturing provides contact around the front, sides and rear of the grip, while the integral SIG accessory rail supports compatible compact lights or other properly fitted equipment. The pistol also includes an extended slide catch lever and a flat XSeries trigger.

This 365XL380COMP variant is the configuration without a manual thumb safety. Safe operation therefore depends on proper handling, a suitable holster that completely covers the trigger guard, secure storage and consistent adherence to the P365 operator’s manual. Keep the trigger finger outside the trigger guard until the sights are on target and the decision to fire has been made.

Sights, Size and Weight

XRAY3 day/night front and rear sights provide a conventional aiming system across varied lighting conditions and remain available if no optic is installed. SIG SAUER lists this model as a micro-compact. Published dimensions include a 6.6-inch overall length, 1.24-inch overall width and 4.55-inch sight radius. Weight is approximately 18.4 ounces with a magazine, giving the pistol an easy-to-carry profile while the XL grip offers additional hand contact.

Setup and Maintenance

Read the SIG SAUER P365 manual before loading or firing. Inspect the pistol and supplied magazines, confirm correct ammunition, and establish reliable operation with the intended load. If an optic or rail-mounted accessory is installed, recheck fasteners as directed and ensure the selected holster fits the completed setup without contacting the trigger.

Routine maintenance should follow SIG SAUER’s instructions for cleaning, lubrication and inspection. Avoid excess lubricant around ammunition or inside magazines, and replace damaged magazines or components rather than attempting an improvised repair. Confirm that any added baseplate, optic or accessory is specifically compatible with this .380 ACP P365-XL configuration.

The P365-XL COMP .380 is designed for owners who want an optic-ready, compensated micro-compact with a longer grip, 12-round capacity and no manual safety. Transfer, magazine-capacity, carry and storage rules vary by location, so buyers should verify all applicable requirements before purchase or use.
