Which, if any, has a special quality at the range over the others?

I once bought a 5" Model 10 and, soon after, bought another just like it (but made 10 years later). The earlier one, made in 1961, became a permanent part of my collection after one trip to the range. The other one shot great, but nothing special in comparison.

Might you have had a similar experience with one of your Combat Masterpieces?
