SIG SAUER Expands P365 XSERIES with P365X ROMEOZero

NEWINGTON, N.H., (March 12, 2021) – SIG SAUER, Inc. is proud to introduce the P365X ROMEOZero, the newest addition to the P365 series of pistols. The P365X ROMEOZero combines the 3.1 inch barrel of the original P365 with the P365XL XSERIES grip module, featuring a 12-round flush fit magazine, with a factory installed ROMEOZero red dot sight, bringing a new level of performance to everyday carry.

“The SIG SAUER P365 series of pistols is the leader in the industry for everyday carry and continues to set the standard for delivering unprecedented capacity in a micro-compact size,” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales, SIG SAUER, Inc. “The introduction of the P365X ROMEOZero further redefines everyday carry by combining the XSERIES features first introduced with the popular P365XL – including the larger grip module and XSERIES trigger – with the shorter 3.1 inch barrel of the original P365, making it an all-around more comfortable concealed carry pistol.”

The SIG SAUER P365X ROMEOZero is a 9mm striker-fired pistol, featuring the XSERIES P365 grip module with an integrated carry magwell and extended beavertail, with the standard 3.1 inch P365 barrel and slide with XSERIES markings, a factory installed ROMEOZero micro-open reflex sight, X-RAY3 day/night front sight, and the XSERIES flat trigger with a 90-degree break. The P365X ROMEOZero ships with two 12-round magazines (15-round magazines available separately).

The SIG SAUER Electro-Optics ROMEZero micro-open reflex sight optimized for everyday concealed carry, and for pistols with slim slides.  The sight features a ruggedized, weapons grade, textured polymer body, Spectracoat™ Polymer lens system, 8 vivid, user configurable daytime illumination levels, MOTAC™ (motion activated illumination system), a highly efficient point source LED emitter for a crisp dot that’s 8 times more efficient than conventional red dots, and an integrated rear sight notch for co-witness with a standard height P365 front sight.

    The p365 series is a great pistol. Period. The R0 optic needs to be made of aluminum and not polymer.

    I’d buy the regular p365 and have it milled for the Trijicon RMR-cc because it’s a duty rated optic.

      I put a Holosun 507C on my 365XL which has the same optic cut. The Outer Impact adapter plate is a hair thicker than I like but being able to put that ACSS Vulcan reticle on such a slim and concealable pistol is A1.

    now they just have to release the slide by itself, they accidentally had the product page active a few months ago.

  3. Antonio says:

    They already have the slide available for $299
    And the Romeo Zero now come with a shroud stain steel shield for free
