K Frame S&W revolvers are something special. My recommendation to non "gun" people for a carry piece is always a K Frame S&W. My personal favourite is the 10/64 or 13/65 in three inch. The round butt preferably but mine was a square. I had one of my own and one of the Govt's for a good number of years and never once felt as though I were at a disadvantage. I shot either exceptionally well and (as I demonstrated more than a couple of times) could worry a hostile greatly wink at 50yds with that little 'Smith.
