"Designed with input from legendary firearms instructor and Delta Force veteran Kyle Lamb of Viking Tactics, the Sig Sauer P320 X-VTAC is a 4.6""-barreled full-size combat-optimized pistol chambered in 9mm Luger. The X-VTAC edition of the P320 takes a P320 X-Full pistol and modifies it with a unique slide profile with coyote PVD coating, slide lightening cuts, grooves along the top surface of the slide, and premium VTAC iron sights. These sights use both a set of fiber optic pipes as well as tritium inserts for high visibility in daylight conditions and glowing night sights in darkness. This slide is also not optics-ready, which later production models have since updated but changed the overall design of the slide to one resembling a standard P320 slide. The black polymer grip module is a medium grip size and houses the X-series Firing Control Unit (FCU) with flat-face trigger. This gun is in fairly well-used condition but shows little wear except for some finish wear on the barrel and barrel hood. The pistol is sold with the factory hard case, three OEM 17-round magazines, and user manual."
