The Sig Sauer P365X ROMEO-X pairs the compact, high-capacity P365 X-Series frame with a pre-mounted ROMEO-X micro red dot for fast, instinctive target acquisition. Chambered in 9mm and built on Sig’s proven P365 platform, the P365X ROMEO-X keeps a small concealment footprint while offering a 12+1 capacity that’s practical for everyday carry or duty backup. The X-Series grip module gives a more ergonomic purchase and slightly longer grip to accommodate higher-capacity magazines without making the pistol bulky, while the ROMEO-X optic reduces sight transition time and improves accuracy on quick shots.
Designed for everyday carry and confident handling in defensive situations, this configuration focuses on controllability, rapid sighting, and reliable function — all in a package that’s easy to carry and comfortable to shoot.

I own over 12 handguns and this is my favorite. Flawless function without any break in. Accurate, low recoil, and easy to rack. I am 75 years old this is very important to us Boomers and to the Ladies (who I highly recommend). The Romeo sight is fantastic. Shrinks my 7 yard group from 5" to 2". Can't go wrong with this Sig.
