I have a FF3 & springer mount on my 97BD. Have not been happy with mount it loosens after about 100 rounds. I have blue lock-tight on every screw. To bad i love the RD Burris FF3. Thinking i might have to go back to original BD sights with my old eyes have trouble with.
T107--I had a similar problem on my 97 with the Springer mount on the CZ's and solved it with a tiny shim cut from either a Diet Dr. can or some realy shim stock. That was 2 years ago. I've used the Springer mount on 4 pistols so far and there is some variation in the dovetails of each CZ I have, whether it be a 75, 97, P-09, or P-07, or even a P-10C. Once you get it shimmed tight, it will stay put. Don't give up on it quite yet. I think the variation is in the pistol dovetails, not the Springer mount, but I'm not sure to be honest. I have three very stable installations right now. I shot my 97 last night at 100 yards with good results.
