Aimtech no-drill optic mount on model 10

[WestKentucky]

I just got a 2nd hand Aimtech K frame optic mount. I had planned to use it on my mode 10-6 heavy barrel but for some reason It doesn’t line up. Seems like the holes are 1/16” or so out of alignment even though the pork chop shaped leg matches the frame contours. Has anyone tried one of these mounts successfully? I think it is likely an issue of the heavy barrel and the associated slightly different frame dimensions.

This is what I have...

Do they still make the original old style? I could use 1 or 2 of them

I think so. What I have is what is shown on the website, and it’s the only thing I recall ever seeing that’s a no-drill mount.
