SIG Sauer’s P320 X-Carry is already a highly-upgraded firearm with the company’s very good, tritium-powered X-Ray3 day/night sights. One of the really neat features of the X-Carry, though, is its ability to readily accept SIG’s Romeo1 red dot sight (RDS). The rear sight is actually integral to a plate mounted atop the X-Carry’s slide, and removing the plate reveals that the slide is pre-cut and drilled for mounting the Romeo1. In this week's NRA Gun Gear of the Week video, American Rifleman’s Joe Kurtenbach walks through the process of equipping an RDS to this red-dot-ready platform.
