Why would you say wheelguns are obsolete? I will guarantee you that a shooter that puts in the practice with a wheelgun will outshoot the vast majority of semi users, especially the DA only models. Also, generally, revolvers come in much more potent cartridges. Personally, if I were ever to want a defense handgun, I think my choice would be a Bulldog in 44 Sp. If I can't stop my target with 6 shots, maybe I shouldn't be shooting? You can reload them darned near as fast as a semi, and I have never heard of a civilian getting in a shootout where running out of shots was an issue (other than on the big screen). I'm sure it must have happened at some point, but I have a sneaky feeling alien abductions are about as common.
