How about a Ruger SP101? Heavy enough to soak up the recoil and comes in a snubby.
Also, Ruger Revolvers will last a lifetime.
I tried that recommendation on the basis that a buddy's very small wife has one and loves it. I suspect it met a somewhat cold reception because she knows with an SP101 she'll have to come looking for it because I'll probably have it.
Charter makes the Undercoverette in .32 H&R Mag but I don't know anything about the quality of Charter Arms other than seeing some bad press here and there?
Unfortunately (as far as choices go) yes, she's set on a revolver. She's competent but in her head not confident with a semi-auto. If god forbid she ever has to use it, she wants it as simple as possible.
I thought about that because of the ability to shoot other rounds like the .32 H&R but there aren't many gun options (if any that you can actually find) and the ammo is pretty expensive from what I've seen.
In the event that the .327 still proved to be too much then she would have the option of hot loaded .32 H&R magnum rounds as well.
S&W use to make the "Lady Smith" its ladies version of the Model 37 IIRC. I think you'll like it.
Find a S&W mdl 60 Ladysmith in .38 Special, or a S&W mdl 66 w/ 2-1/2" barrel!!
Here's what the Ladysmith looks like:
I picked that Ladysmith up, at a FNRA Banquet a few years ago, for less than $300.00! Look closely at the serial #!!
NICE score at a great price!
