SIG Sauer is the first company to offer a compact carry pistol with a slide-mounted reflex sight straight out of the box. The new P320 RX comes equipped with a Romeo1 reflex sight, which is designed to give shooters a more intuitive sighting option while equipping the handgun with a rugged and reliable optic. The Romeo1 optic features a 3-MOA red dot with multiple intensity settings and is built with a magnesium housing for added strength. The suggested retail price for the P320 RX with the Romeo1 included is $869.
