Now is the time to enhance your P320 with the U.S. Military's official sidearm slide and optic assembly, available only at the SIG SAUER webstore. Easily equip your P320 with the factory-mounted, American-built ROMEO-M17 featuring SIG SAUER's proprietary SIG-LOC mounting system. The ROMEO-M17 boasts a fully enclosed, sealed, and purged optical system for ultimate protection against all elements. Its low deck height allows for absolute co-witness with the existing standard-height sights. With 15 brightness settings, including 3 optimized for GEN 3+ Night Vision, you enjoy exceptional adjustability to your preference, with 3 options of reticle display: circle only, dot only, or a circle/dot combination. Powered by a single side-mounted CR2032 battery, the ROMEO-M17 is designed to function for 50,000 hours before needing a replacement.

The U.S. Military selected this optic for its advanced technology, which includes MOTAC (Motion Activated Illumination), MAGNETAC (Magnetic Activation), and D.A.R.C. (Dark Adaptive Reticles & Coatings).
