Viridian RFX44 Compact Closed Emitter Green Dot Sight w/ For Glock Adapter Review

First Thoughts on the Viridian RFX44 Compact Closed Emitter Green Dot Sight w/ For Glock Adapter

The market is saturated with red dot sights, but the Viridian RFX44 Compact Closed Emitter Green Dot Sight w/ For Glock Adapter promises something different: a green dot, enclosed emitter, and a design optimized for modern pistols. Viridian is known for pioneering green laser technology, so I was eager to see if their experience translated well to this compact optic. This sight is aimed at shooters who demand rapid target acquisition, durability, and enhanced visibility, even in challenging conditions.

My primary reason for seeking a new optic was to improve target acquisition speed in low-light scenarios. I’ve found that traditional red dots can sometimes bloom or blend into the background, especially in bright sunlight or against red-toned targets. The promise of a brighter, more easily discernible green dot was a major selling point.

Unboxing the RFX44, I was immediately struck by its compact size and seemingly robust construction. The 6061 aluminum housing felt solid in my hand, and the sleek design was aesthetically pleasing. The weight felt appropriate, not too heavy as to add noticeable bulk to my Glock, but substantial enough to inspire confidence.

I considered the Trijicon RMR and Holosun 507C before settling on the Viridian RFX44. While the RMR is a gold standard, its open emitter design is a known weakness. The Holosun offered similar features, but Viridian’s reputation for green laser technology and the unique top-mounted electronics of the RFX44 swayed my decision. Initial impressions were positive, I was excited to mount it and head to the range.

Real-World Testing: Putting Viridian RFX44 Compact Closed Emitter Green Dot Sight w/ For Glock Adapter to the Test

First Use Experience

My first range session with the Viridian RFX44 was at an outdoor range on a partly cloudy day. I mounted it on my Glock 19 using the included adapter. The initial zeroing process was straightforward, with easily audible and tactile adjustments.

The green dot was noticeably brighter and clearer than any red dot I’ve used. Even against bright targets, the 5 MOA dot stood out remarkably well. I immediately noticed faster target acquisition times compared to my previous setup.

One minor issue arose after about 100 rounds: the dot seemed to flicker momentarily. I suspect this was due to a slightly loose battery connection. Tightening the battery cap seemed to resolve the issue, however.

Extended Use & Reliability

After several months of use, including weekly range sessions and a practical pistol course, the RFX44 has proven to be quite reliable. The aluminum housing shows no signs of wear despite being subjected to holster draws and minor bumps. Cleaning the lens is simple, and the enclosed emitter design has kept dust and debris at bay.

The battery life seems consistent with Viridian’s claims. I have not had to replace the original CR1632 battery after many hours of use. The INSTANT-ON feature is fantastic, ensuring the optic is always ready when I need it.

Compared to my previous open emitter red dot, the RFX44 is a clear upgrade. It offers superior visibility, durability, and peace of mind. The enclosed design, in particular, has made a significant difference in its reliability.
