I'm a bit fuzzy, - is the Airlight the 317?
I bought one to check out. Worked extremely well, my bud bought one & I right-away got one for The Wife.
Tickled in every aspect except that you will keep checking to make sure the thing's still on your belt - weighs next to nothing. I find this a good thing for why we bought 'em.
They seem to be very ammo non-dependent = shoots everything to date just as well - certainly good enough. Coke cans at 75 yards pretty usual.
We've no hand disabilities, so your remarks don't apply to us. Actually, a bit heavier revolver would absorb recoil better than a more lightweight handgun.
I'd suggest getting with some friends & let her shoot some of theirs & see what it is she likes best. Only way to be sure. It'll be her gun afterall & she should decide what she likes.
Worst case though, you'll have a nifty li'l shooter that you'll like.
Get her her own! I can't tell you more emphatically.
As an aside, when sighting in my own, I noticed the bullets were keyholing at 7 yards (first shots). Yada, yada re "failure analysis attempt - turned out the barrel wasn't rifled! A first for me & The Smith "customer service guy" said that it "couldn't happen" due to all their QC/in-process-stuff ... right. Been there/done that in a past life & literally anything can (& will) happen.
Anyway, they fixed it - whoop & duh.
Good li'l shooter. I like mine/ours & so do all who use 'em.
Might not be the best for yours.
Let her pick her own by actually using what's out there.
Sorta sorry for the rambling .....
