Trijicon RMR/SRO Adapter Plate Review

First Impressions of Trijicon RMR/SRO Adapter Plate

The Trijicon RMR/SRO Adapter Plate promises a seamless solution for mounting the popular Trijicon RMR or SRO red dot sights onto Sig Sauer pistols. As someone who’s spent years customizing firearms for optimal performance in both tactical and recreational settings, I was intrigued by the prospect of a dedicated adapter. My initial hope was that this plate would provide a secure and reliable platform, eliminating the guesswork often involved in universal mounting solutions.

I recently acquired a Sig Sauer P320 XCompact, and I’m a big fan of the Trijicon SRO for its large viewing window and crisp dot. To be able to meld the two together for fast target acquisition became my priority. The primary reason for choosing this plate over others was the Trijicon name; they are a hallmark of quality optics. My assumption was that their adapter plate would also uphold those standards.

Upon receiving the adapter plate, I immediately noted its sleek, black anodized finish. It was also evident the plate was made of steel. The overall construction appeared robust, but I was surprised by how lightweight it felt. Initial excitement tempered slightly with a nagging feeling of “too good to be true,” given the $43.49 price point.

Real-World Testing: Putting Trijicon RMR/SRO Adapter Plate to the Test

First Use Experience

My first test was at my local indoor range. I wanted a controlled environment to assess the adapter’s performance and co-witnessing capabilities. Mounting the Trijicon SRO onto the plate and then attaching the plate to my Sig Sauer P320 XCompact was straightforward, at least initially.

The first concerning moment was when tightening the screws. The screws provided seemed unusually long. Despite my cautious approach, I felt a slight “give” as if the threads weren’t perfectly matched. After firing the first magazine through the pistol, I noticed that the SRO had already begun to loosen.

Extended Use & Reliability

Over the next few weeks, I subjected the Trijicon RMR/SRO Adapter Plate to more rigorous testing, including several outdoor range sessions and some dry-fire practice at home. The initial loosening issue persisted. I had to constantly re-tighten the screws after every magazine.

There are no obvious signs of wear and tear on the plate itself, thanks to the anodized finish. However, the mounting screws showed wear from repeated tightening and loosening. Disappointingly, this plate requires constant attention, making me question its overall reliability. I have used other mounting options from different manufacturers that require no maintenance after installation.

Breaking Down the Features of Trijicon RMR/SRO Adapter Plate

Specifications

• The Trijicon RMR/SRO Adapter Plate is designed specifically for mounting Trijicon RMR or SRO optics. This guarantees compatibility with those red dot sights.
• It’s constructed from steel with an anodized matte black finish. This increases durability and provides corrosion resistance.
• The adapter is designed for Sig Sauer handguns. This limits its compatibility to only those pistol models.

Performance & Functionality

The Trijicon RMR/SRO Adapter Plate‘s primary function is to provide a stable mounting platform. Unfortunately, the loose screw issue undermined this core purpose. The plate itself sits flush and looks aesthetically pleasing. However, the inability to maintain a secure connection between the SRO and the slide makes it unreliable for serious use.

The major weakness is the questionable quality and fit of the provided screws. Modification of the screws might solve the problem, but a customer should not have to modify a product to make it work. It unfortunately does not meet my expectations, especially considering the Trijicon name.

Design & Ergonomics

The steel construction and matte black finish are aesthetically pleasing. The plate’s low profile minimizes added bulk to the pistol. The design is simple and straightforward, with no unnecessary frills.

However, the ergonomics are negatively impacted by the constant need to check and tighten the screws. A secure and reliable mounting solution should allow the shooter to focus on shooting, not hardware maintenance. The Trijicon RMR/SRO Adapter Plate did not provide that experience.

Durability & Maintenance

The steel construction suggests that the plate itself will last a long time. However, the longevity of the screws is questionable, given how easily they wear down with repeated use. The anodized finish makes the plate easy to wipe clean.

Ensuring the screws are properly torqued and frequently checked becomes a necessary maintenance task. Otherwise, the SRO will start to wobble. This plate requires vigilance.

Accessories and Customization Options

The adapter plate comes with mounting screws. There are no other included accessories. The Trijicon RMR/SRO Adapter Plate is specific to Sig Sauer pistols and Trijicon RMR/SRO optics. This significantly limits its customization options compared to universal mounting systems.

Who Should Buy Trijicon RMR/SRO Adapter Plate?

The Trijicon RMR/SRO Adapter Plate might be suitable for casual target shooters who prioritize aesthetics and aren’t overly concerned with absolute reliability. If the screw issues can be resolved, it would be perfect for competitive shooters needing rapid target acquisition and durability.

Anyone using their Sig Sauer pistol for self-defense or tactical applications should skip this product. The risk of the optic loosening during a critical situation is unacceptable. Before using this plate, a user should purchase new screws that are the correct length and pitch.

Conclusion on Trijicon RMR/SRO Adapter Plate

The Trijicon RMR/SRO Adapter Plate is a disappointing product, especially considering the Trijicon name. While the design and materials are adequate, the critical flaw with the provided screws undermines its core function. The $43.49 price tag is not justified given the need for potential modification and constant maintenance.

I would not personally recommend this adapter plate until Trijicon addresses the screw issue. There are more reliable and cost-effective mounting solutions available on the market. Save your money and opt for a more reputable plate.
