Meprolight MPO-PRO S Tritium Night Sight Review

What Happened When I Tried the Meprolight MPO-PRO S Back Up Tritium Night Sight, – 1 out of 5 models

The Meprolight MPO-PRO S Back Up Tritium Night Sight, – 1 out of 5 models, from the renowned manufacturer Meprolight, promises a reliable and always-ready sighting system for Glock pistols. The key selling point is the combination of blacked-out rear sights with a low-profile tritium front, designed for maximum visibility and a dependable backup should electronic optics fail in low-light conditions. I was intrigued by the simplicity and redundancy offered, especially given my background in tactical applications.

My need for these sights stemmed from a growing reliance on red dot optics on my Glock pistols, coupled with a nagging concern about battery failure during critical situations. While I appreciate the speed and precision of red dots, I understand that electronic devices can and will fail. Having a robust backup sighting system that doesn’t rely on batteries seemed like a smart insurance policy.

Unboxing the Meprolight MPO-PRO S Back Up Tritium Night Sight, – 1 out of 5 models, I was immediately impressed by the solid feel of the metal construction. The sights appeared well-machined and the tritium vial in the front sight glowed faintly even in daylight, a promising sign for its low-light performance. The blacked-out rear sights had a clean, no-nonsense appearance.

Compared to other tritium night sights I’ve used, like Trijicon HDs or Ameriglo Spartans, the Meprolight offering stood out for its intentional focus on co-witnessing with red dots. Many night sights are quite tall, and this obscures the optic. These, however, seemed lower-profile than most.

My initial impression was one of cautious optimism. I was excited about the potential for a reliable and unobtrusive backup sighting system, but I was also slightly concerned about how well the low-profile tritium front sight would perform in truly dark conditions compared to sights with larger tritium vials.

Real-World Testing: Putting Meprolight MPO-PRO S Back Up Tritium Night Sight, – 1 out of 5 models to the Test

First Use Experience

I first tested the Meprolight MPO-PRO S Back Up Tritium Night Sight, – 1 out of 5 models at an indoor shooting range, initially during daylight hours to assess their daytime visibility and then transitioning to low-light scenarios. I mounted them on my Glock 19 MOS, which also has a Holosun 507C red dot. The installation process was straightforward.

During daylight, the blacked-out rear sights provided a clean and uncluttered sight picture, allowing me to focus on the front sight and the target. The low-profile design did not interfere with my red dot’s sight picture. In low-light conditions, the tritium front sight provided a visible aiming point, although it was noticeably dimmer than some of the larger tritium sights I’ve used.

After the initial range session, I was pleased with the co-witnessing capability and the clarity of the sight picture, but I felt a small amount of concern about the nighttime brightness of the front sight.

Extended Use & Reliability

After several months of consistent use, including weekly range sessions and a few low-light training exercises, the Meprolight MPO-PRO S Back Up Tritium Night Sight, – 1 out of 5 models have held up remarkably well. There are no signs of wear and tear on the metal bodies of the sights, and the tritium vial continues to glow consistently.

I’ve also tested these sights during outdoor nighttime scenarios, including a simulated home defense drill and a nighttime hog hunt (where, thankfully, the red dot didn’t fail!). The tritium front sight was adequate for close-range engagements, but in very dark environments, target identification became more challenging compared to using a weapon-mounted light in conjunction with brighter tritium sights.

Maintenance has been minimal; I simply wipe them down with a clean cloth after each range session. They continue to perform as expected and provide a reliable backup sighting system for my red-dot-equipped Glock.

Compared to previous experiences with other night sights, the Meprolight MPO-PRO S Back Up Tritium Night Sight, – 1 out of 5 models excels in its unobtrusive design and seamless co-witnessing capability. While the tritium brightness might not be the absolute highest on the market, the overall package is well-suited for its intended purpose.
