Another alternative is the MMC adjustable sight. It's similar to a Novak, but adjustable for elevation with a screw, and windage like any other "fixed" sight.
It would seem suited for different loads where impact points may rise or fall, since windage adjustments should not really change much in most situations.
The Bomar style sights are good sights, and as Roscoe said, offer a very good sight picture... The Wilson's have a "pyramid shaped" blade as an option. While they might be a little less snag proof that a Novak, or Heinie, they are still much better than a typical rear blade found on the older, Enhanced style Colt's.
I did carry a Gold Cup at one time, and found it very comfortable, and never had a problem catching on the sight. Of course... YMMV
Good Luck...
