Low Profile Red Dot Mount for Ruger Security 9 Compact
Seems to be a good product. Mounting was easy and the fact that it indexes automatically thanks to the it using the same threaded hole used by the factory sight is a plus. My Sig Romeo Zero went on without a hitch.

Low profile mounting plate for Ruger S9
This sight fit perfect,but not out of the package. You have to fit to get it on,but easy to do,get a small gunsmith triangle file,file one direction keeping the file flat so you keep the angle. Took me about 20 mins to file. I would only file a few strokes at a time and tried fitting until it would mostly slide on then I used a hammer and punch and tapped it in place. My sight fit perfect then I bore sighted ready for the range to zero. I had another mount on my pistol but didnt have enough elevation since mount was too tall. This mount is a lot lower so I should have plenty adjustment. I would recomend this product and super fast delivery.

Quality but…
This is a nice quality piece but it will not fit the Ruger security 380. This was my fault. The security 380 and the security 9 are very similar in dimensions, I figured it would work but the dovetail is slightly different on the 380.
