I didn't want to spend the money to have my slide machined, so I decided to try this adapter. Installation went smoothly with the proper sight pusher, and once everything was tightened with thread locker, it felt extremely solid. The optic has held zero and I haven't had to retighten the screws. Very happy with this purchase.

I was impressed as soon as I opened the package. The machining is very clean, the finish matches my slide well, and the plate fit tightly without any filing or modification. After properly installing my optic, everything has remained secure through multiple range trips.

I wanted to add a red dot to my Ruger Security 9 but didn't want to send the slide out for machining. This mounting plate turned out to be exactly what I was looking for. The machining quality is excellent, the finish blends nicely with the factory slide, and the plate fits securely once installed. I appreciated that multiple screw sets were included because it made matching my optic much easier. After following the installation instructions, applying thread locker, and torquing everything properly, the optic has remained rock solid. After several trips to the range, my zero hasn't changed and the mounting screws have stayed tight. Considering the price and the quality, this is one of the best upgrades I've made to my Security 9. I'd confidently recommend it to anyone looking for a reliable optic mounting solution.

The product itself appears to be well made, but removing the factory rear sight on my pistol was much more difficult than I anticipated. Once I finally got everything installed, the plate worked correctly. New buyers should understand this isn't necessarily a five-minute installation and having the proper tools or professional installation can make the process much easier.

The plate itself is well machined, but I initially assumed every optic mounted the same way. After reading the instructions more carefully, I realized my optic uses the rear mounting holes instead of the locating pins. That's on me, but I think the packaging could emphasize that even more clearly. Once I figured it out, everything worked.

I've had this plate installed for a couple of months now and couldn't be happier. The installation required replacing the rear sight, which was expected, and once everything was properly installed, the plate locked up securely. I've fired several hundred rounds without the optic shifting or the screws backing out. The fit between the slide and the plate is excellent. For anyone wanting to add an optic to a Ruger Security 9 without permanent modifications, this is an outstanding solution. Just make sure you use the recommended torque and thread locker during installation.

I compared several mounting plates before deciding on this one. The machining is clean, the finish matches the slide nicely, and the optic sits low enough to feel natural. My only suggestion would be to include a printed compatibility chart in the package since there are so many supported optics. Other than that, it's an excellent product.

Installation was straightforward as long as you have the proper tools to remove the rear sight. The plate fits my Ruger Security 9 securely, and once everything was torqued down with thread locker, it stayed solid through several range sessions. The included screw selection was also a nice bonus since I didn't have to order additional hardware.

I was looking for a way to mount a red dot without having the slide machined, and this plate was exactly what I needed. It replaced the factory rear sight perfectly, fit tightly, and the supplied hardware worked with my optic. Very satisfied with the purchase.
