My range time with the optic/pistol combo was thorough to say the least. The P365 XL comes with an optics-ready slide, so it was just a matter of attaching the ROMEOZero with two screws - fast and easy. On the Rangeįor me, installation was pretty simple. The ROMEOZero is available in both 3 and 6 MOA. It offers eight vivid daytime settings with a point source LED emitter that is highly efficient and parallax free, offering a much crisper dot than other conventional red dots. Daytime illumination is user configurable. This is literally unrivaled in the world of micro reflex sights. The ROMEOZero has a 10-year battery life. The MOTAC system aids tremendously in preserving battery life, which is pretty substantial to begin with. Why is that useful? Because the optic powers back up at that same setting. It saves the last setting the optic was on when it powers down. This technology powers up illumination immediately when it senses motion and will power down when the optic is still.

MOTAC technology (Motion Activated Illumination System) powers the ROMEOZero. The added durability and resistance to both the housing and lens could significantly make a difference and makes EDC with the new optic a simple task. Concealing a gun with an optic incorporated can lead to issues and damage caused by repeated holstering and unholstering. Both of these features are specifically useful given SIG designed the optic primarily for everyday concealed carry. The Spectra Coat HD Polymer Lens system offers 10 times the resistance to impact over other traditional glass lenses. SIG made the ROMEOZero Weapons Grade Ultralite Polymer housing, which gives it the element of durability. The ROMEOZero enables rapid target acquisition in an everyday carry package at an iron sight price.” The SIG ROMEOZero Build The sight features a ruggedized, Weapons Grade textured polymer body and the Spectra Coat HD Polymer lens system. SIG describes this optic as, “The fastest, most accurate, ultra-compact micro reflex sight - the ROMEOZero has been optimized for everyday concealed carry and pistols with slim slide profiles. For starters, the stippling pattern incorporated on the optics housing is made to match the P365 and P365XL to give a cohesive and integrated look.

Aesthetically, the new red dot is quite different from others in the SIG Optics family. Having been among the first to test the new P365 XL, I was also given the opportunity to test one of the ROMEOZero prototypes. VIDEO: First Range Test With the All-new SIG P365 XL Pistol A New Look
