Description
The P320 X-Full is built for shooters who want a full-size duty pistol that can carry optics without committing to a fixed red dot from the factory. The slide is cut with a direct optic mount, so you can run a dot when you want one and rely on the X-RAY3 night sights the rest of the time — those sights use a tritium front element that remains usable in low or no light, which matters if this pistol is going anywhere near a home defense or duty role.
The striker-fired action removes the hammer from the equation, which keeps the grip profile clean and eliminates the variable of hammer-down versus cocked-and-locked carry. The manual safety gives you a positive mechanical block if that fits your training, without requiring it of shooters who prefer to rely on trigger discipline alone. The 4.7-inch barrel gives the slide enough travel and the gas enough time to cycle the action with consistent authority, and it keeps the sight radius long enough that the fixed irons are genuinely useful at defensive and range distances.
The NIT finish refers to Sig’s Nitron process, a physical vapor deposition treatment applied to the slide that resists corrosion and reduces surface friction. Two 10-round steel magazines ship with the pistol, which means you have a spare loaded and ready without an additional purchase. The modular serialized chassis that defines the P320 platform means the fire control unit can be moved into a different grip module down the road if your preference changes.
