First Impressions of Meprolight MPO-DS Open Emitter 3.5 MOA Dot Pistol Sight with RMSc/JPoint Footprint
For years, I’ve relied on iron sights and, more recently, enclosed emitter red dots on my pistols. I resisted open emitters, fearing their vulnerability to the elements and potential for lint buildup to obstruct the dot. However, the promise of a wider field of view and faster target acquisition, combined with a budget-friendly price point, finally convinced me to try the Meprolight MPO-DS Open Emitter 3.5 MOA Dot Pistol Sight with RMSc/JPoint Footprint. Meprolight, a name synonymous with rugged and reliable firearm accessories, piqued my interest, and the MPO-DS seemed like the perfect entry point into the world of open emitter pistol optics.
My need was simple: to improve my speed and accuracy with my everyday carry pistol, a Sig Sauer P365. The factory iron sights were adequate, but I knew a red dot would offer a significant advantage in low-light conditions and during rapid target transitions. The low profile of the Meprolight MPO-DS was particularly appealing, as I didn’t want to add excessive bulk to my already compact pistol.
Upon unboxing the Meprolight MPO-DS, I was immediately impressed by its sleek, minimalist design. The black anodized aluminum housing felt solid and well-made, a reassuring sign from Meprolight. It felt surprisingly lightweight, which is crucial for a pistol optic.
I had been considering the Holosun 407K and the Shield RMSx, both popular choices for subcompact pistols. I opted for the Meprolight MPO-DS due to Meprolight’s reputation for durability and the significantly lower price point. I figured it would be a good way to determine if I enjoyed the open emitter design before investing in a more expensive optic.
My initial impression was one of cautious optimism. I was excited to mount it on my P365 and hit the range, but also slightly apprehensive about potential issues with dot washout or durability. I was eager to see if this budget-friendly optic could live up to the Meprolight name.
Real-World Testing: Putting Meprolight MPO-DS Open Emitter 3.5 MOA Dot Pistol Sight with RMSc/JPoint Footprint to the Test
First Use Experience
I first tested the Meprolight MPO-DS at my local indoor shooting range. The range offers a controlled environment, allowing me to focus on the optic’s performance without external distractions. I ran approximately 200 rounds through my P365, focusing on drills that emphasized speed and accuracy at various distances (7-15 yards).
The optic performed admirably in the well-lit range environment. The 3.5 MOA dot was crisp and easy to acquire, and the automatic brightness adjustment seemed to work well, adapting to the ambient lighting. I found the target acquisition to be noticeably faster than with iron sights.
One minor issue I observed was a slight delay in the automatic brightness adjustment when transitioning from a dimly lit area to a brighter one. It wasn’t a deal-breaker, but it was noticeable. I experienced no other issues during this initial range session.
Extended Use & Reliability
After several months of regular use (averaging 2-3 range sessions per month), the Meprolight MPO-DS has held up remarkably well. I’ve subjected it to various conditions, including rain, high humidity, and dusty environments during outdoor shooting drills.
The optic has shown no signs of significant wear and tear. The anodized finish remains intact, and the dot remains clear and bright. I’ve noticed a slight accumulation of lint on the emitter on occasion, but it’s easily remedied with a quick blast of compressed air.
Maintaining the Meprolight MPO-DS is simple. I clean the lens with a microfiber cloth and occasionally use compressed air to remove dust or debris from the emitter area. Battery life has been excellent; I’m still on the original CR2032 battery.
Compared to my experience with enclosed emitter optics, the Meprolight MPO-DS requires slightly more frequent cleaning, but the wider field of view and faster target acquisition outweigh this minor inconvenience. Overall, the Meprolight MPO-DS has exceeded my expectations for a budget-friendly open emitter red dot.
