The P320 from Sig Sauer is a striker-fired, modular, polymer framed pistol using a unique serialized fire control group. Since the fire control group is the serialized portion, users can easily change calibers, frame size, and slide length without purchasing a second, or third, pistol.
The Full Size Tacops variant includes 4 21 round 9mm magazines, a full size grip, full length slide, standard height fiber-optic and tritium sights, and non-threaded barrel.
