I would suggest skip the .22 Mag. In a handgun it does not offer any advantage over .22 lr that is is noticeable. I would get a used Ruger MKII or MKIII, and later get a rifle in .22 Mag.
Aside from performance, price is a big factor. .22 Mag cost way more to shoot.
Oh I had a RR it did what it was designed to do without any problems. I gifted it to my nephew. He still shoots it, and it still works just fine.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
