Dave - although I am in the "12 gauge pump camp", I certainly understand your situation. I think you have a good "master plan" for breaking in your wife and daughter! When I went through the same thing with my wife, I bought an old Ruger Mark I pistol at a gun show. She really enjoys shooting it, and her only complaint is the 6 7/8" barrel - she would prefer the shorter 4" one.
Please let us know what you end up with, and best of luck! <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />Tom
