The SIG Sauer P320 X-Full is a full-size, duty-grade 9mm built for accuracy and optics-first performance: a 4.7? X-slide over an ergonomic X-Series polymer grip delivers a long sight radius and excellent recoil control, while the striker-fired X trigger provides a crisp, consistent pull. Factory-equipped with a ROMEO-RS Pro reflex sight and XRAY3 co-witnessable iron sights, the pistol is optics-ready out of the box and includes a MIL-STD Picatinny rail for lights or lasers. It ships with two 17-round steel magazines for 17+1 capacity, wears a durable Nitron finish on the steel slide, and offers ambidextrous controls and modular grip options—making it a versatile choice for service use, range work, or anyone who wants a full-size platform optimized for red-dot use.
