I've decided to carry an SP101 while off duty. Now I just have to choose a configuration. I'm going with .357 for the added versitility but will probably still carry .38+P ammo in it. Now, should I go with the 2 or 3 inch barrel? I know in theory the extra inch will give me a little bit more control but is it worth the extra bulk? I've shot a three inch and love the feel, will the two inch be that different? I also like the idea of a hammerless for concealability and I shoot double action anyway. If I go with the three inch could a good smith take the hammer down for me?
