The P365XL XSeries configuration features a 3.7 in barrel and an extended micro-compact grip module that provides a longer sight radius and full-hand purchase while retaining a slim profile. The modular stainless-steel fire control unit is the serialized core, allowing straightforward grip module swaps within the P365 family.
The slide is matte black with front and rear serrations, chamfered muzzle shoulders, and an optics cut with a cover plate installed. Dovetailed iron sights include a green-dot front and a square-notch rear, offering a clear, durable sight picture.
The flat-faced trigger is characteristic of the XSeries and provides a straight, consistent press. The frame is polymer with mild texturing and an extended beavertail, and it incorporates a single-slot accessory rail for lights or other compact rail-mounted tools.
Standard capacity is 12+1 in 9mm Luger. Two 12-round steel magazines are included; they have witness holes marked 5 and 12 and are marked MADE IN USA. Overall factory dimensions are approximately 6.6 in in length, 4.8 in in height, and 1.1 in in width. Made in the USA.
