The Sig Sauer P365 is a revolutionary design and introduces a new type of carry pistol, the micro double stack or micro sub compact. It holds 10 rounds in a semi flush magazine. The SAS has an integral rear sight. It is a fiber optic design and makes the top of the slide snag free. The rest of the pistol has been radius cut to make sure it will not snag on anything coming in or out of concealment.
