I totally understand k-frames with 3" barrels such as the s&w model 13 which was the fbi issue during the 70's and 80's. You get a full length ejector rod, great balance, ccw capability and only a slight loss in terms of velocity as compared with the 4 inch barrel. The 2" s&w model 10/64 however baffles me. If you are going to put up with the 2" ballistic performance you might as well go with the J-frames/taurus mod 85 size revolvers and save youself a lot of weight. Anyone feel differently? Thanks.
