But for day in-day out, night in-night out, canoeing, camping or back up for the big gun while in the high timber after elk, the M66 makes a strong case. Stainless construction with nearly the same action smoothness, lack of a full under barrel rib, grips that fit and reasonable weight make it my first choice .
Very good point rodfac
Owning both the 66 and 27, if I had to choose one for daily carry, it would be the 66. It's what I used to often primarily cc before I went to the J-frame. But in every other aspect, it would be the 27.
