sell it and buy a heavier gun
Carl
I agree. A heavier frame would be my first choice.
Other than that, a lighter bullet, ported barrel like my Taurus Tracker would help, and lastly - rubber grips that fit her hand.
My wife has small hands and even has trouble with the Tracker (.357) even though it has rubber grips and ported barrel. She just doesn't like it - even with 148-grain wadcutters at 800-850 fps.
Good luck.
