S&W has a bunch of options...models 38, 42, etc....
she needs to go to a range that rents guns, in my opinion, and try a number of guns chambered in .38 spl / or .357 mag ....with and without hammers ( even like an old model 10 - or maybe a model 19 or 66 ) ....so she can decide what suits her for size, grip, weight, sights, hammer or no hammer...and how it shoots for her ....( she may like some of the air weight models / or she may hate them )....but bottom line, make her decison on what "she" likes the best on looks and on how it shoots.
