Dovetail plate for optics?

[Kingston73]

I’ve got a holosun 407k with nothing to put it on and a 75 compact that needs new sights.  I am wondering how good or bad the plates that fit into the rear sight dovetail work?  I know the red dot would be higher than a slide cut but other than that what are the good and bad points of using one of these?
I’m looking at something like this: https://egwguns.com/trijicon-rmr-sro-holosun-407c-507c-mount-for-cz-75-75-sp-01-phantom-85-97-p01-p07-p09-and-pcr

I had a sig dovetail plate and Romeo1 on my SP-01 for a few years before I decided to have it milled. It worked fine, held zero and stayed on. I would expect EGW should work fine as well based on their reputation.

I have used the EGW dovetail plates on a 75B and 97B, as well as P-09 and P-07, and a 1911.  They work fine.  You may have to add a 2-5 mil brass shim if the dovetail itself is a little wide.  I've seen some variation in the dovetails that is beyond the control of any of the dovetail mount suppliers.  I just cut shim stock from a small sheet and add as needed.  I think my P-09 and 97B mounts have been in place for nearly 10 years, and the 75B one has been on and off several pistols.  I've used the red dots in dovetail mounts for 100 and 200 yard shooting videos for years without a problem. as well as for many bullseye matches.  That said, sure, if you can get the slide cut it makes for a nicer installation, but the dovetail mount can be very reliable if done correctly.

I've got an EGW plate on a Shadow 2 with a 407k. Works great. Performance wise, I can't tell any difference from my milled pistols. Looks wise, not so much.
