I'll be the lone voice of dissent here on 3" revolvers. I have a 2.5" Model 66 which is one of my favorite carry guns. I once had a 3" Model 66, but I eventually sold it, because it just never had the feel to it for me that the shorter one did. I originally bought it, because of all of the hype you read about how great the 3" revolvers are. Being a big fan of snub-nosed revolvers, the 3" Model 66 even looked funny to me. The whole longer ejector rod advantage is WAY overblown. If you handle the gun correctly, by flipping it upside down in your off hand and giving the ejector rod a firm pop, even the most stubbornly stuck cases will come right out every time. If I need a longer barrel than a 2.5",I'll just carry my 4" Model 686.
