The P365XL XSeries configuration delivers a longer sight radius of 5.6 in and a 12+1 capacity in a slim 1.1 in-wide profile. The XSeries flat trigger promotes a straight, consistent press, and the striker-fired, locked-breech action offers familiar P365 ergonomics in the XL size.
The stainless steel slide wears SIG's Nitron finish and includes forward and rear serrations. It is optics-ready with an RMSc-footprint cut and a cover plate installed, giving you the option to mount a micro red dot that fits this pattern.
Sight acquisition is handled by tritium night sights: a front blade with a green ring and H3 marking, paired with a tritium square-notch rear. The XSeries polymer grip module adds an extended beavertail for control.
The dustcover features SIG's single-slot accessory rail for a compact light or accessory that matches this rail type. The modular, serialized FCU allows grip module swaps, and this non-MS configuration has no external manual safety. Overall length is 6.6 in, height 4.8 in, and unloaded weight is 20.7 oz with magazine.
