The new P320 RXP Series comes loaded with ROMEO optics.

SIG Sauer recently announced the release of a new series of pistols featuring SIG optics. The SIG P320 RXP Series pistols include the P320 Full-Size, Compact, XFULL and XCOMPACT RXP. Each pistol includes a factory-installed ROMEO1PRO Reflex Optic.

SIG Sauer P320 RXP Series

“Red Dot Reflex Optics have long been the standard amongst the military and law enforcement, and are rapidly growing in popularity amongst commercial consumers. The number one barrier to universal adoption of the red dot in the commercial market is the installation and zeroing of the optic on the pistol,” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales, SIG SAUER, Inc. “SIG SAUER is the only manufacturer in the firearms industry that can truly integrate a firearm and an optic into a single system right from the factory to completely eliminate the installation hesitation of the red dot. With the introduction of the SIG SAUER P320 RXP series of pistols we are leading the Red Dot Revolution so end users can easily achieve greater performance and increased accuracy with one simple purchase.”
