SIG Sauer P365XL XSeries 9mm, 3.7-inch Barrel, Optics-Ready, X-RAY3 Sights, Black Nitron, 12+1 — Includes SIG Sauer Weapon Light and Two 12-Round Mags
This SIG Sauer P365XL XSeries brings the XL-length 3.7-inch barrel, XSeries ergonomics, and a flat-faced trigger together in a compact 9mm package. It is optics-ready with the factory cover plate installed and comes equipped with SIG X-RAY3 day/night sights. This example includes a SIG Sauer weapon light fitted to the proprietary P365 rail, plus two 12-round steel magazines, making it a well-appointed carry-ready setup.
The XSeries grip module features enhanced texturing for secure control, and the Nitron-finished slide has forward and rear serrations for confident manipulations. It is striker-fired and configured without a manual safety. The slide is marked "P365" with a prominent "X," identifying the XL XSeries configuration.
The optics-mounting cut allows easy addition of a compatible micro red dot when desired, while the installed cover plate keeps the slide streamlined. SIG’s X-RAY3 tritium sights provide a bright green-ring front and two-dot tritium rear for consistent sighting in varied light conditions.
This pistol retains the proprietary P365 accessory rail (non-1913), and the included SIG Sauer weapon light is designed for this interface and is already installed. The package comes with the factory case, manuals, and two 12-round magazines with flush baseplates.

The P365XL XSeries format balances concealability with shootability via the longer slide and barrel. The flat-faced XSeries trigger offers a consistent press, while the XSeries grip module promotes a solid hold. The Nitron-finished slide with both front and rear serrations supports reliable manipulation in daily use.
Factory X-RAY3 night sights are installed, pairing a high-visibility green-ring tritium front with a two-dot tritium rear. The optics-ready slide features a mounting cut and arrives with the cover plate installed, preserving a clean top profile until an optic is added.
This model uses SIG’s proprietary P365 rail, and this pistol includes a SIG Sauer weapon light already mounted to that rail for immediate low-light utility. Capacity is 12+1 with the included steel magazines, and the pistol is the non–manual-safety configuration.
Made in the USA, this P365XL XSeries is designated by part number 365XL-9-BXR3P-FX-RS and carries the XL-specific 3.7-inch barrel. The slide is marked "P365" with a prominent "X," clearly identifying the XSeries configuration.
