Trijicon RMR Mounting Kit for Glock MOS and Springfield OSP Models Review

Let’s Dive into Trijicon RMR Mounting Kit for Glock MOS and Springfield OSP Models

The Trijicon RMR Mounting Kit for Glock MOS and Springfield OSP Models is a seemingly simple collection of parts. However, it bridges the gap between high-performance optics and popular pistol platforms. Trijicon, a name synonymous with rugged and reliable optics, offers this kit to ensure a secure and proper fit for their RMR (Ruggedized Miniature Reflex) sight on Glock Modular Optic System (MOS) and Springfield OSP (Optical Sight Pistol) handguns. This isn’t just another accessory; it’s a necessary component for anyone wanting to run an RMR on these pistols.

I transitioned to red dot sights on my pistols a few years back and never looked back. I wanted a Trijicon RMR on my Glock 19 MOS, but quickly realized the screws that came with the RMR were too long. The need to find the correct mounting hardware is what led me down the path to this kit.

Unboxing the Trijicon RMR Mounting Kit was rather underwhelming. It’s a small package containing a sealing plate, two short screws, and a hex key. The components look well-machined, but the simplicity is striking.

Compared to universal MOS adapter plates that try to accommodate multiple optics, this kit is specifically designed for the RMR. This focused design promised a more secure and lower-profile mount. I also considered buying individual screws, but opted for the kit to ensure compatibility and proper sealing.

Initially, I was a bit surprised that Trijicon didn’t include these essential parts with the RMR itself, especially considering the optic’s premium price point. However, my excitement to finally mount the RMR outweighed the initial disappointment. This kit felt like the final piece of the puzzle.

Real-World Testing: Putting Trijicon RMR Mounting Kit for Glock MOS and Springfield OSP Models to the Test

First Use Experience

I tested the Trijicon RMR Mounting Kit at my local shooting range, mounting the RMR on my Glock 19 MOS. The installation process was straightforward thanks to the correct screw length. The sealing plate fit snugly between the RMR and the MOS cut, creating a tight seal.

The range was relatively dry and warm, so I didn’t get to test it in extreme conditions. However, the mount felt solid and secure during firing. There were no signs of loosening or shifting of the optic after several magazines.

The RMR sat low and co-witnessed perfectly with my suppressor height iron sights. This immediate co-witness was a huge plus for transitioning to the red dot. It helped improve my target acquisition speed, and the accuracy was on par with what I was expecting.

Extended Use & Reliability

After several months of regular use, the Trijicon RMR Mounting Kit continues to perform flawlessly. The mount remains secure, and there’s no evidence of corrosion or loosening despite exposure to cleaning solvents and occasional rain. The durable finish shows minimal wear.

I’ve put several hundred rounds through my Glock 19 MOS with the RMR mounted using this kit. The optic hasn’t shifted or lost zero. The peace of mind knowing the optic is securely mounted is invaluable.

The kit requires minimal maintenance. I simply wipe down the sealing plate and screws when cleaning the pistol. It significantly outperforms cheaper, generic mounting options that often require constant tightening or exhibit premature wear.
