Few thoughts. 1). Shooting is like showering, if you don't do it regularly, you stink. Just more practice I reckon is all that's needed. 2) my wife is 5'2 and a little gal with small hands, but like Iggy's wife, she really likes a Colt .45, GI spec. 3) You mention that she does real well with the first gun you gave her, maybe just practice getting really good with that one then. Neat thing about this hobby is that it's up to you, have fun, be safe, and enjoy the time together.
