Well, cause I enjoy swimming upstream ;-). As for a 4" barrel, I'm looking for a 2-3" because my wife intends to use this as her carry weapon. Considering the relatively low power requirements for revolver, recoil isn't going to be much of an issue except perhaps for my wife.
In all truth, we have no intentions of shooting many official matches, the locals have no problem with my wife shooting her ported 4" taurus. I just figure my next gun purchase will be a legit IDPA gun. I suppose I can always do some trigger work on a k-frame so my wife can manage it properly.
Thanks everybody for your wonderful suggestions, I have a feeling we'll be browsing the gun shops and shows for a good deal on a used wheelgun..
