The Sig Sauer(R) P320(R) RXP Compact Semi-Auto Pistol with Romeo1 Pro Optic in 2-Tone is a lightweight polymer-frame, striker-fired pistol that points on target instinctively, while remaining concealable with it's compact size. The P320 RXP comes with a Romeo1 Pro Reflex Sight that allows rapid target acquisition with both eyes open and threat focused targeting. The parallax-free sight has unlimited eye-relief for consistent point-of-impact with your weapon, regardless of the eye's position behind the sight. Suppressor-height sights allow co-witnessing with the reflex sight. The P320 RXP has a smooth, consistent trigger pull allowing precise shot placement as well as rapid, controlled fire. An ergonomic textured grip provides a nonslip hold, even with sweaty hands. The frame features an integral 3-lug Picatinny rail for attaching aftermarket lights and lasers. A serialized, stainless steel inner frame assembly allows interchangeability with aftermarket grip modules according to one's hand size. The matte-finished stainless steel slide features front and rear cocking serrations for a solid grip when manipulating the slide. The slide is nicely chambered and de-horned to allow effortless draw and re-holstering.
