This is a SIG Sauer P365 XL, a larger version of the original P365, but which still retains good "conceal-ability". This is a 9mm semi-auto with a 3.7-inch barrel, a flat trigger with a 90 degree break, X-RAY3 Day/Night Sights, and an "optics-ready" slide which accommodates Romeo Zero and RMSc Optics. The P365 XL was designed to be just a bit longer, taller, and heavier than the original P365, which results in a higher-capacity (12 as opposed to 10) and a more comfortable handgun for shooters with large hands. There are 2 magazines included.
