The Sig Sauer P320X Compact pistol in 9mm with a factory-mounted ROMEO-X reflex sight and black finish (brand part no. 320XC9BXR3RXX) pairs the XCompact grip module with an integrated red dot for a complete optics-ready carry package out of the box. Sig Sauer builds the pistol on a stainless steel frame with a Nitron-finished slide and an X-Series flat trigger, and the SHIELD/RMSc optic footprint supports future sight swaps. Night sights back up the ROMEO-X for co-witness aiming, and two 15-round magazines ship with the pistol. Among optics-ready semi-auto handguns, this P320X Compact configuration favors carriers who want a red dot pre-installed.
