NEWINGTON, N.H., (January 16, 2020) – SIG SAUER, Inc. is pleased to introduce red dot accuracy right out-of-the-box with the P320 RXP Series pistols. The P320 Full-Size, Compact, XFULL, and XCOMPACT RXP pistols combine the latest advancements in reflex optics with a factory-installed ROMEO1PRO Reflex Optic from SIG SAUER Electro-Optics with the award-winning P320 pistol.

“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.”

The P320 RXP Full-Size and Compact Series Pistols are 9mm striker-fired pistols that come with a factory-installed ROMEO1PRO Open Reflex 6MOA sight and suppressor height backup sights, ambidextrous slide catch lever, reversible magazine catch, and a modular polymer grip module available in small, medium, and large. The intuitive 3-point takedown of the pistol requires no trigger pull for disassembly, and safety features include a striker safety and disconnect safety. The P320 Full-Size RXP comes with (2) 17-round magazines, and the P320 Compact RXP comes with (2) 15-round magazines.
