Well first is M-27,M-625-45 colt,2nd Model 44 special,M-57. I have to say the .357 for the recoil in the n frame. I do like the .45 colt and .44 special neck and neck. .41 mag is right there as well but third all are great to shoot.
I loved my model 27, but it was more of a collector piece and I was really more of a shooter kinda guy at the time. Eventually sold it to guy who was more into storing them in a safe.
Since my 28-2 isn't home yet, the jury is still out, but I'm betting it will take top honors.
