I love carrying my small revolvers. The idea of using one as your primary is fine with me, two is even better!
I have considered carrying two year round and never having my M&P9 on me. I tend to carry my 9 during the winter when concealing is much easier, people wear heavier cloths etc, but those little Js are hard to give up. I often carry two IWB-appendix, one at 10 o’clock, one at 2. It is comfortable, light, and affords an easy draw with either hand. The only concern I really have is the low round count.

Every time I see a used J-frame for sale in a gun shop I feel like I have to rescue it like a lost puppy.
