The SIG Sauer P320 Full-Size RX is a factory-integrated reflex optic pistol in the P320 family. This RX configuration ships with a ROMEO1 reflex sight installed and co-witness SIGLITE suppressor sights.

Built on a Nitron finished stainless steel slide, the Full-Size RX features a 4.7 in barrel, 17-round 9mm capacity and an accessory rail for lights/lasers. The pistol is striker-fired and includes internal safeties (striker safety and disconnect safety); manufacturer specifications list an overall length of 8.0 in and a weight of approximately 29.5 oz (with magazine). Manufacturer and procurement listings show the RX Full-Size offered bundled with 17-round magazines and, in some government procurement configurations, supplied with a hard case and cable lock. The RX models are supplied from the factory with the reflex optic pre-installed and zeroed.
