Meprolight MPO-S Open Emitter 3 MOA Dot Pistol Sight with RMSc/JPoint Footprint Review

First Impressions of Meprolight MPO-S Open Emitter 3 MOA Dot Pistol Sight with RMSc/JPoint Footprint

For over a decade, I’ve been immersed in the world of tactical gear, from setting up backcountry shelters to advising law enforcement on their loadouts. When pistol red dots started gaining traction, I remained skeptical of their durability and practicality, especially for everyday carry. However, the promise of faster target acquisition and improved accuracy intrigued me, eventually leading me to the Meprolight MPO-S Open Emitter 3 MOA Dot Pistol Sight with RMSc/JPoint Footprint.

I needed a compact, reliable optic for my EDC pistol, something that wouldn’t snag on clothing and offered a clear sight picture in all lighting conditions. After researching numerous options, the Meprolight stood out with its reputation for ruggedness and its compatibility with the popular RMSc footprint. This footprint meant easy mounting on my Sig P365XL without the need for adapter plates.

The unboxing experience was straightforward; the optic felt solid and well-built. Its low profile design immediately struck me as ideal for concealed carry. Comparing it to a Holosun 507K and a Trijicon RMRcc, I found the MPO-S to offer a slightly larger window than the RMRcc. It also came at a more attractive price point than either option.

My initial impression was positive. I was excited to see if the Meprolight MPO-S could live up to the hype and improve my EDC setup’s performance. Its compact design and reputation for durability had set high expectations.

Real-World Testing: Putting Meprolight MPO-S Open Emitter 3 MOA Dot Pistol Sight with RMSc/JPoint Footprint to the Test

First Use Experience

My first range trip with the Meprolight MPO-S Open Emitter 3 MOA Dot Pistol Sight with RMSc/JPoint Footprint was eye-opening. I tested it on my Sig P365XL at an outdoor range in varying lighting conditions. Zeroing was simple, requiring only minor adjustments to get on target at 15 yards.

The optic’s auto-brightness adjustment worked surprisingly well, adapting smoothly to both bright sunlight and overcast skies. The 3 MOA dot was crisp and clear, and I quickly got used to the sight picture. My initial concern about an open emitter being susceptible to rain was put to rest as the sight performed flawlessly even when subjected to simulated rain with a spray bottle.

Extended Use & Reliability

After several months of carrying the Meprolight MPO-S daily, I can attest to its durability. There are no visible signs of wear and tear despite being subjected to the rigors of everyday carry. Cleaning the lens is simple with a microfiber cloth, and I haven’t experienced any issues with moisture or debris affecting the dot’s visibility.

Compared to my previous experience with a Holosun optic, the Meprolight feels more robust and better suited for demanding conditions. The battery life has also been impressive. After all these months, I am still on the original battery and see no signs of dimming.

Accessories and Customization Options

The Meprolight MPO-S does not come with an extensive array of accessories, focusing instead on core functionality.

• Aftermarket Slides: Many pistol slides are available with pre-cut RMSc footprints.

The lack of included accessories is offset by the optic’s compatibility with numerous third-party options. This allows users to tailor their setup to their specific needs and preferences.
