Let’s Talk About USED Trijicon RMR RM50 Pistol Mount, Sig Sauer w/o – 1 out of 21 models
The USED Trijicon RMR RM50 Pistol Mount, Sig Sauer w/o – 1 out of 21 models is a specific mounting solution designed by Trijicon to attach their Ruggedized Miniature Reflex (RMR) sight to certain Sig Sauer pistols. Given that it’s a used item, understanding its purpose, compatibility, and condition becomes even more crucial. This mount promises a secure and low-profile platform for adding a red dot sight to your Sig Sauer, enhancing target acquisition speed and accuracy.
My journey to acquiring this particular mount started with a desire to modernize my older Sig Sauer P226. I wanted to explore the benefits of a red dot optic without the expense of milling the slide or purchasing a completely new firearm. The Trijicon name is synonymous with quality and ruggedness in the optics world, so finding a used RM50 mount seemed like a cost-effective way to dip my toes into the red dot pistol world.
Upon receiving the mount, the first thing I noticed was its robust construction. Even though it’s a used item, the aluminum seemed durable, and the finish, while showing some signs of wear, appeared to be intact. The mount felt solid in my hand, instilling confidence that it could withstand the recoil of the pistol.
Comparing it to other mounting options like universal dovetail mounts or slide-milling services, the RM50 offered a balance of security and relative ease of installation. While universal mounts often compromise stability, slide milling is a permanent and more expensive modification. The USED Trijicon RMR RM50 Pistol Mount, Sig Sauer w/o – 1 out of 21 models appeared to be a happy medium, provided it was compatible with my specific Sig Sauer model.
My initial reaction was cautiously optimistic. The potential for cost savings was appealing, but the “used” aspect introduced an element of uncertainty about its long-term reliability and fit. It would all come down to how well it performed on the range.
Real-World Testing: Putting USED Trijicon RMR RM50 Pistol Mount, Sig Sauer w/o – 1 out of 21 models to the Test
First Use Experience
My first range session with the USED Trijicon RMR RM50 Pistol Mount, Sig Sauer w/o – 1 out of 21 models was at an outdoor shooting range on a relatively clear day. I mounted the RMR to the mount and then carefully installed the mount onto my Sig Sauer P226, making sure to follow Trijicon’s installation instructions meticulously. I started with a few magazines of target rounds to ensure proper zeroing and observe how the mount held up to the recoil.
The mount felt secure, and the RMR held its zero fairly well after the initial adjustments. However, I did notice some slight movement of the mount after about 50 rounds. I had to re-tighten the screws to ensure a snug fit.
Ease of use was relatively straightforward, although aligning the mount perfectly during installation required some patience and a torque wrench to avoid over-tightening the screws. The only real surprise was the need for periodic re-tightening, which raised concerns about its long-term reliability.
Extended Use & Reliability
After several range trips and approximately 500 rounds fired, the USED Trijicon RMR RM50 Pistol Mount, Sig Sauer w/o – 1 out of 21 models showed some signs of wear. The finish started to exhibit minor scratches, and the screw threads showed slight wear.
Despite the cosmetic imperfections, the mount continued to function, although the issue of loosening screws persisted. I found myself checking and re-tightening them after every 100 rounds or so.
Maintenance was simple, involving cleaning the mount with a soft cloth and applying a small amount of thread locker to the screws to help prevent them from loosening. While it outperformed cheaper universal mounts in terms of stability, the need for frequent maintenance was a bit disappointing compared to a brand-new, professionally installed mounting solution.
Breaking Down the Features of USED Trijicon RMR RM50 Pistol Mount, Sig Sauer w/o – 1 out of 21 models
Specifications
- Manufacturer: Trijicon. They are a well-respected name in the optics industry.
- Model: RM50. This specifies it’s designed for the Trijicon RMR.
- Compatibility: Sig Sauer (specific models, without a pre-existing optic cut). This is the most important factor to verify before purchasing.
- Material: Aluminum (likely 7075-T6 for strength). This provides a balance of lightweight and durability.
- Finish: Anodized (typically black). This enhances corrosion resistance.
- Mounting Style: Replaces the rear sight (dovetail mount). This offers a relatively low-profile setup.
- Weight: Approximately 1 ounce. This minimizes added weight to the pistol.
These specifications matter because they dictate the mount’s compatibility, durability, and overall performance. Aluminum construction ensures it can withstand recoil forces, while the mounting style influences how securely the RMR is attached and its co-witnessing capability with iron sights (if possible). The “used” condition, however, introduces a variable that needs to be carefully considered alongside these specs.
Performance & Functionality
The USED Trijicon RMR RM50 Pistol Mount, Sig Sauer w/o – 1 out of 21 models performs its primary job of attaching an RMR to a compatible Sig Sauer pistol reasonably well, provided the screws are properly torqued and checked regularly. Accuracy is maintained once the RMR is zeroed, and the low-profile design minimizes obstruction of the sight picture.
The mount’s main strength lies in its relatively easy installation and the ability to add a red dot sight without permanent modifications to the pistol. The biggest weakness is the tendency for the mounting screws to loosen over time, which can affect zero and reliability.
It met my basic expectations of enabling me to use an RMR on my Sig Sauer, but the maintenance requirement was a drawback. A brand-new mount might offer greater long-term reliability.
Design & Ergonomics
The build quality is generally good, given that it’s a Trijicon product. The aluminum construction feels solid, and the black anodized finish provides some level of protection against corrosion.
The design is relatively user-friendly, with a straightforward installation process. However, achieving perfect alignment and proper torque requires some attention to detail.
Durability & Maintenance
The durability of a used mount is inherently questionable compared to a new one. The existing wear and tear can shorten its lifespan.
Maintenance involves regular cleaning and checking/tightening the mounting screws. Applying thread locker is recommended to prevent loosening.
Accessories and Customization Options
The mount itself doesn’t offer significant customization options. Its primary purpose is to provide a platform for attaching a Trijicon RMR.
Compatibility with other brands is limited to RMR-footprint red dot sights. Aftermarket screws might be an option to improve security and prevent loosening.
