P 22 is a good gun but get her a 38
I took my wife out for the first time and started her on a .38 since everyone seems to think that is a good idea. I am lucky she loved me enough to continue after the first two shots. The noise, flame, and recoil were enough to ruin her on shooting forever.
Luckily we were at a range with rentals and they had a P22. She really liked it and now will do some shooting with a 38 but likes shooting the P22. Starting with a .38 in her case was a huge, huge mistake.
Be careful, go slow.
