Another thing to consider with this kind of pistol, would she like a plow or birdshead type of handgrip? They're really different in how they fit the hand and be comfortable while having control.
The Barkeep does come with shorter barrels of around 3.5" to I believe 6" if wanted, compared to the regular Rough Riders that start around 4.75" and go up to 16", but either one, the owner can change out the handgrip frames to have either style, as they all are interchangable.
What's nice, is one can get a different grip frame, directly from Heritage for about $30-$40 or so.
I wish Ruger had different handgrip frames (brass, stainless, case-color) and colored cylinders to purchase on the cheap like Heritage does, to really bling out my Ruger Super Wrangler Convertible (22LR and 22Mag).
I know Wrangler's grip frame will interchange with the Super Six and I believe a Blackhawk model, but finding either one's parts is about as expensive as what my SW cost me back in March. But, one can't get the cylinder's from Ruger and have a drop-in, as they're hand fitted and just slightly different in timing, or something that's different, as some owner's have found when trying to convert their standard Wrangler to 22Mag cylinder that they've purchased from a Super Six model on Ebay.
