" Recoil is quite soft compared to magnum revolvers, so the only issue little girls would have is the grip size."
Depends on what cartridge and what kind of revolver.
Like I say in the video, I've shot 44 mag out of a snub nose Ruger .44 mag revolver, but that's the only one stronger that I've shot that was noticeably "worse" than the G20.
Load up a G20 with high power 10mm and you've definitely got yourself a hand cannon.
The facts however are simple: the polymer frame does a great job absorbing recoil.
