The P365 XL format combines a 3.7-inch barrel with the longer XL grip module, extended beavertail, and an integrated carry magwell. This configuration provides added control while keeping overall dimensions well-suited to concealed carry or mid-sized roles.
The slide is optics-ready with a Shield RMSc footprint. The rear sight plate has been removed, leaving the optic mounting screw holes open. A TG-H3 tritium front sight with a green dot is installed; no optic or rear sight is included.
Controls and handling are enhanced by forward and rear cocking serrations on the Nitron-finished slide. The striker-fired XSeries flat-faced trigger delivers a crisp, 90-degree break for consistent shots. The overall finish is black.
The modular FCU architecture supports the P365-series ecosystem, and the dust-cover accessory rail accommodates compatible lights or accessories. Three magazines are included: one 15-round and two 12-round steel magazines, with grip sleeves as applicable for a seamless fit.
Made in the USA, this model ships with the SIG factory hard case and both IWB and OWB holsters, providing immediate carry flexibility and secure storage.
