Rory,
I have a couple of 99CDs that have a dovetail cut in the barrel for a rear sight and two d&t holes, one fore and one aft, for the Williams rear sight. Is that common?
That would be odd on a 99CD, but I believe it. As Lightfoot said - we've seen this on several models. Barrels that were pre-made with dovetails before they switched to Williams, and then they added the screws, slapped on a Williams and put it on the gun. Definitely on 99A's and I think a couple 99C's.
It's odd on a 99CD because the 99CD's were always made to have a Williams rear sight, never a dovetail. So those are probably 99CD's that got barrels made for another model. Are they really late 99CD's?
