The Next Generation of the P320 PRO is here, delivering all the performance and reliability that made the M18 the choice of the U.S. Military, now outfitted with the most advanced features from the X series of pistols. The M18 PRO includes a factory mounted ROMEO-M17 red dot optic featuring a ruggedized aluminum housing, aspheric glass lens for zero distortion, and is fully enclosed and sealed, for ultimate protection from the elements. This pistol and optic are fully blacked out. The PRO’s Flat Blade Trigger provides an increased tactile response for greater accuracy.

  • ROMEO-M17 Red Dot Sight installed on the slide
  • Black X-Carry grip module
  • PRO Flat Blade Trigger
  • (2) 21rd magazines (1) 17rd magazine
  • Carry length 3.9″ slide

This firearm is not available with a manual safety. A manual safety – when engaged – is designed to mechanically prevent the firearm from discharging when the trigger is pressed, either intentionally or unintentionally. You should consider whether a manual safety on a handgun is right for you based on your experience level and intended use, keeping in mind best practices for safe firearms handling. It is possible for the trigger to be unintentionally pressed even under normal handling circumstances.

A manual safety is designed to augment, not replace, safe firearm handling practices. You are responsible to protect against unintentional trigger movement while carrying any firearm. Even if you elect to purchase a pistol equipped with a manual safety, you must ensure that the trigger is not contacted in any circumstance other than when you intend to fire the pistol, particularly if you elect to carry your pistol with a round in the chamber.   If you have a round in the chamber and the trigger is pressed to the rear, the pistol will fire, absent an engaged manual safety. 

The M17 and M18 pistols have been selected by the US Military as the official sidearm, and the ROMEO-M17 is the only optic that is truly designed specifically for this pistol.  All other optics have many disadvantages and make several compromises.  The ROMEO-M17 does not.  This is an American-built MIL-SPEC red dot truly worthy of the SIG SAUER name.

*Please Note – The ROMEO-M17 pistol red dot sight utilizes SIG SAUER’S proprietary SIG-LOC mounting interface and only fits SIG SAUER M17/M18 military issue, and commemorative pistols with a single optics plate mounting screw. This sight will not fit any other pistols.



  • A fully enclosed, sealed, and purged optical system, for ultimate protection from the elements
  • Mounts from underneath the pistol slide, re-using the MHS pistol rear sight block and sight block screw
  • 7075 Aluminum housing
  • Integrated gas deflector on the front of the housing
  • Machined anti-reflection grooves on all rear surfaces for reduced glare
  • Extremely low deck height, allowing a full sight picture and co-witness with standard-height sights
  • SIG-LOC™ (SIG Leverage Optimizing Connection) proprietary mounting interface, for the ultimate optic/pistol lockup.
  • A high-efficiency point source LED emitter, with 2 MOA dot/32 MOA circle reticle.  The reticles are independently selectable (circle only, dot only, or circle/dot combination).
  • Independent brightness adjustment buttons that are recessed within a protective plate which can be activated even with gloves on. Buttons have bump features above UP and below DOWN, so they can be determined by feel.
  • 15 brightness settings, with 3 of the settings optimized for use with Gen 3+ NV devices
  • A side-mounted CR2032 battery compartment with a threaded battery cap, for easy battery changes without the need to remove the optic from the firearm.  The cap is slotted and knurled, for use with or without tools.
  • Minimum continuous runtime of 20,000 hours, at medium brightness setting
  • 2 drainage holes machined in the sides of the housing, just behind the rear sealed window, to allow pooled liquid to escape when the optic goes from a vertical position (such as in a holster) to a horizontal position (such as shooting)
  • Windage and elevation adjustments have tactile clicks.  Adjustment screws are slotted, for use with any small flat-blade tool.  Adjustment resolution is 1.5 MOA per click.
  • MOTAC (Motion Activated Illumination)
  • MAGNETAC (Magnetic Activation)
  • D.A.R.C. (Dark Adaptive Reticles & Coatings)
