I suppose mine is a pinch-based style
Not really. It is just the old 1st Gen V groove style sight. Nothing pinched about it. The 'pinched frame' refers to the fact that the rear sight was 'pinched in' about 1/4" from the rear of the sight.
Here is the rear sight on an old 1st Gen Bisley.
Here is the squared off rear sight on a 2nd Gen Colt on the left, and an Uberti/Cattleman on the right. Personally, I prefer the 2nd Gen sight. Easier for guys with poor eyesight to see.
