You cant go wrong with a 4" 19 or 66. I am fortunate to own many of both colt and smiths. They are all good. Many people will say a model 27. While I have owned them forever I dont agree. If I really am going to carry a N frame, it will be my .44 special model 24-3 in 4". I think I recall dobies answer, and I can agree with it too. While I also own a 3" 66-3 I got to say its fine, but not my 1st choice. If I want to hunt to eat I want a slightly longer barrel and larger caliber. That brings me back to the model 24-3 4". Its lighter than a 6", less bulky and weighs less than a 29, I belive it doesnt weigh any more and even maybe less than my 66 for cc. Hell, they are all good .38 and up.
