Adequate
I purchased this mount to replace the pic rail on my Ruger 22/45 Lite for Holosun 507 mounting. The locator pins on the mount are set screws, not pins, and the mount is still large enough to prevent using the holster I want to carry the pistol in. It does mount the sight, but required loc tite to keep the locator screws from moving and is only adequate, far from ideal. It will do until I find a better mounting solution.

shadow mount
Bought this and put it on. When mounted over the ejection port shell casings hit it. When mounted forward optic pushes against the leather opening in the side slinger holster. Not a good combo. As I want to use the holster I'll need a different mount. If spent cases didn't hit it all would be well. Low rating because I can't use it.

Perfect Fit
This item was recommended to me by a friend. It arrived well documented and was super easy to install. My optic sits right where I want it. Great for my Mark IV.

Easy to install and solid mount
Great, streamlined sight mount for my Vortex Venom on my MK IV. Lowers height over bore significantly and reduces the number of parts required to mount the sight. Very solid mount as well.

Ruger MK Shadow Mount.
Product appears to be made of good quality material and fits nicely. I did have to go to the local hardware store to get a threaded insert. As the mount only uses two of the Three mounting holes. The provided threaded plugs are to large. The C-More sight only fight after removing the rear sight from my TacSol Barrell requiring a second threaded plug of an additional size. All and all nice product great company.

Excellent Versatile Mount
A well made very versatile mount that accepts a wide range of red dot sights. Does not require removing the rear sight for most red dots which is a plus.

Shadow mount
Perfect, versatile. Holds up great. My only qualm is that it doesn t come in stainless finish. But regardless not enough of a problem to say anything bad.

Shodow Mount
I have a Holosun 507 mounted on my Mk IV Hunter with the Shadow Mount. No better system to help old eyes be competitive. The mouth is rock solid and gives lots of option for different dots and mount location.

shadow mount
I really like everything Tandemkross makes for the Ruger Mark 4. Everything does just like they say, "makes good pistols great." Initially, I had the mount with the sight mounted closer to the rear, but I just couldn't seem to get a good sight picture. So, I flipped it around and front mounted it. Made a HUGE difference for me! My only issue is price. It's getting harder to justify spending money, at al really, in the Biden economy. I can't ding a product I LOVE because it costs me a little. So, 5-stars it is.
