While I agree that plates will almost always be less desirable than a dedicated cut, I still think Shadow Systems should still consider an adapter plate.
Hopefully QC would be consistent across the various slide lengths and from year to year that such a plate would fit tightly into the cutout. If not, some plastic spacers could be used to get a very solid fit. I'd think with the longer mounting screws SS is using now we would have the next best thing to a dedicated cut.
Point for similar discussion; when I switched from my 508T red to my 508T green I found some slight variance in body length. The red reticle version fit quite snugly with the appropriate spacer. The green version did not because the housing is fractionally smaller. I called SS to enquire about getting a new spacer. The tech told me to just use the existing spacer and to squirt a little red loktite in to help fill the gap.
