What Makes USED EDEMO Trijicon RMR/SRO Adapter Plate, Sig – 1 out of 17 models Stand Out?
In the world of pistol customization, mounting a red dot optic has become increasingly popular. The USED EDEMO Trijicon RMR/SRO Adapter Plate, Sig – 1 out of 17 models offers a solution for Sig Sauer pistol owners looking to add a Trijicon RMR or SRO without expensive milling. Its promise of easy installation and durable construction makes it a compelling option for those seeking enhanced accuracy and faster target acquisition.
My journey to finding this adapter plate started with a desire to improve the usability of my Sig P320 for both range shooting and potential concealed carry scenarios. I wanted to transition from iron sights to a red dot optic, specifically a Trijicon RMR, but didn’t want to permanently alter my slide. This adapter plate seemed like the perfect middle ground, offering a non-destructive mounting solution.
Upon receiving the adapter plate, the first thing I noticed was its compact size and relatively lightweight design. The black hard anodized finish appeared robust, suggesting it could withstand regular use and exposure to the elements. The included screws, though small, seemed appropriately sized for the task at hand.
I considered other options, including direct milling of the slide and other adapter plates from different manufacturers. Direct milling was ruled out due to its permanent nature and higher cost. I chose the EDEMO plate due to its specific design for Sig Sauer pistols and its reputation for reliability within the online shooting community.
My initial impression was cautiously optimistic. The plate appeared well-made, but I was slightly concerned about whether a used adapter plate would truly hold zero consistently. I was eager to get it mounted and test its performance firsthand.
Real-World Testing: Putting USED EDEMO Trijicon RMR/SRO Adapter Plate, Sig – 1 out of 17 models to the Test
First Use Experience
The EDEMO adapter plate was first tested at my local outdoor shooting range. I mounted it on my Sig P320 using the provided screws and then attached my Trijicon RMR. The initial installation process was straightforward, taking only about 15 minutes with basic hand tools.
The range conditions were typical for a summer afternoon: sunny and slightly humid. I ran approximately 200 rounds through the pistol, focusing on target acquisition speed and maintaining a consistent zero. There were no immediate issues with the adapter plate shifting or loosening during the initial shooting session.
The immediate improvement in target acquisition was noticeable. The red dot made it significantly easier to quickly and accurately engage targets at various distances compared to the iron sights. However, I did observe that the dot seemed to wander slightly after prolonged strings of fire, which raised some concerns about maintaining a precise zero over time.
Extended Use & Reliability
After several weeks of use, the USED EDEMO Trijicon RMR/SRO Adapter Plate, Sig – 1 out of 17 models has held up reasonably well, but with a few caveats. I’ve put approximately 1000 rounds through the pistol with the adapter plate installed, across multiple range sessions and even a few informal shooting drills in a controlled environment.
While the plate itself shows minimal signs of wear and tear, the screws have required periodic tightening. Despite using thread locker (Loctite), I’ve noticed that the optic mounting screws tend to loosen after 200-300 rounds. This requires constant vigilance and a small toolkit in my range bag.
Compared to other mounting solutions I’ve used in the past (specifically, direct milling on other pistols), the EDEMO adapter plate does not offer the same level of rock-solid stability. While functional, it’s clear that adapter plates inherently introduce a potential point of failure due to the added layer of interfaces. Still, for the price, it has allowed me to experiment with red dots on my Sig.
Breaking Down the Features of USED EDEMO Trijicon RMR/SRO Adapter Plate, Sig – 1 out of 17 models
Specifications
- Compatibility: Designed specifically for Sig Sauer pistols to mount Trijicon RMR or SRO optics. This tailored fit is critical for proper function and alignment.
- Material: Precision machined, likely from aluminum, and hard anodized. The anodized finish provides a layer of protection against corrosion and wear.
- Included Accessories: One adapter plate, two plate mounting screws, and two optic mounting screws. Having all necessary hardware included simplifies the installation process.
- Mounting: Utilizes existing mounting points on the Sig Sauer pistol slide. This eliminates the need for permanent modifications like milling.
These specifications matter because they directly impact the plate’s reliability, ease of installation, and overall durability. The material and finish determine how well it withstands recoil and environmental factors, while the compatibility ensures a secure fit. The use of existing mounting points makes the process reversible, a major advantage for those hesitant to permanently alter their firearm.
Performance & Functionality
The USED EDEMO Trijicon RMR/SRO Adapter Plate, Sig – 1 out of 17 models performs its primary function adequately: it allows you to mount a Trijicon RMR or SRO on a compatible Sig Sauer pistol. Accuracy is generally good, provided the mounting screws are consistently checked and tightened.
The main weakness is the potential for the optic to shift or loosen over time, particularly during extended shooting sessions. This is a common issue with adapter plates, as they introduce an additional interface between the optic and the slide. It does meet my expectations for a used part, but perhaps not a new one.
Design & Ergonomics
The build quality of the EDEMO adapter plate is decent, with a clean and functional design. The hard anodized finish provides a sleek look and added durability.
From an ergonomics perspective, the plate adds a minimal amount of height to the optic, which is generally acceptable. There’s a small learning curve associated with using a red dot, but the adapter plate itself doesn’t introduce any unique challenges.
Durability & Maintenance
Based on my experience, the EDEMO adapter plate appears to be reasonably durable. There are no signs of cracks or deformation after several months of use.
Maintenance is straightforward, primarily involving periodic cleaning and tightening of the mounting screws. Regular inspection of the plate and screws is recommended to ensure optimal performance and safety.
Accessories and Customization Options
The primary function of the EDEMO adapter plate is to enable the use of Trijicon RMR and SRO optics on Sig Sauer pistols. Beyond the optic itself, there aren’t any significant customization options directly related to the adapter plate.
Compatibility with different optic models within the RMR/SRO footprint is a key consideration. While designed for these optics, some minor fitting might be necessary depending on the specific model and manufacturing tolerances.
