I have read numerous threads on how many feel that the 3913 is the best that S&W has ever produced. I personally have never handled or shot a 3913, so I cannot agree or argue their point. I do have a 6906 that I feel is the best and carry daily. I added the Hogue grips which made a world of difference. There are times that the bulk of the grip does print when carried concealed. I'd like to hear some opinions from those who have or had both pistols.
