Good that she wants to shoot semi-auto and not revolver.
Even someone who plans only to carry around a little .38 snubbie should test at someplace where they can rent a full-sized GLOCK for the test or something. If you test using a revolver, you can ONLY carry a revolver, and I figure, why limit yourself? I think I finally convinced an older gentleman friend of the wisdom of this, but he argued with me for a good while before he decided that maybe testing with a semiauto was a good idea...the only gun he owns is a Rossi .38 snub.
A little 2" .38 special is harder to keep on target than a small semiauto of whatever caliber, though a laser sight system in the grip can help revolver accuracy somewhat if you have one. My friend doesn't...his has a narrow wood grip, like a classic "chief's special" type gun. I let him shoot my PT92, my Bersa, and my CZ-75B, which finally sold him on the idea.
I passed the test with my Bersa .380 Thunder, but for the heck of it, I re-shot the CHL test target on my own, roughly approximating the course of fire using my CZ-75B in .40 S&W....and did marginally better, with less stray shots at 15 yards...no misses and no "3s", while I did get 1 "3" with the smaller Bersa at 15 yards.
