One thing would be certain. Unless that babe is 6" tall and 180 lbs, she isn't going to be using that tool.
Other than that, it isn't anybody's business what she buys, unless, of course, it is cigarettes.
.44 Magnum is not that difficult to use after some practice. I have seen several women that were not 6' tall and 180 Lbs. use that tool quite well.
