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.
