The FN Five seveN is the one I have, circumference of the grip is about the same as a Beretta 92.
Ruger, PSA, and now especially S&W's offerings are much slimmer due to metal mags, so it should be better for smaller handed folks.
That said, it's not a 'universal grip' like a G43X of single stack. So may need to get granny a PS90 instead
I don't get the attraction but they had quite a bit of ammo for it at the local farm supply store when I stopped in recently.

I don't own a 5.7, but borrowed a friend's FN for a three day dirtbike ride through the Mojave and really loved the gun. We were trying to go light and the gun fit the bill. It was light, carried lots of ammo, and shot far with accuracy. I agree that shooting out to 100 yards is a pretty easy task. I would have loved to have a dot. It was easy to hit jackrabbits and they seem to react as if hit by a .22 Hornet from a rifle (not a very scientific observation, but an observation nonetheless.). I get this is a total niche gun, but for some it might have a purpose and for others it might just be for fun.
The price of the FN is ultimately what kept me away, but these are getting into the impulse range for me. I am definitely not going to be a beta tester, but if these last awhile they would make a good desert companion.
I am glad to see another 5.7 out there.
