The Pro Full-Size RXP configuration is built around a stainless-steel slide with a Nitron black finish and factory optic cut. It features front and rear cocking serrations and suppressor-height iron sights, with the front blade dovetailed and marked TG-H3.
The included Sig Sauer Romeo 1 Pro Red Dot is the ROMEO1PRO model with 1x magnification and a red reticle. It uses an open-emitter design with an aluminum housing and comes installed with the SIG steel protective shroud.
The X-Series style, flat-faced trigger provides the P320 Pro’s distinctive control feel. Ambidextrous slide-catch levers and a full-length dust cover with a 4-slot MIL-STD-1913 rail support duty-ready handling and accessory mounting.
The full-size polymer grip module wears a SIG medallion and the pistol is chambered in 9mm Luger with a 17+1 capacity. The 4.7 in non-threaded barrel complements the slide length for a balanced, full-size setup.
