As so many have said, Ruger MK 2 or 3 (the only problem with these are putting them back together after cleaning, taking apart is easy)
Buckmark...
You can find either of these used if you keep looking there are FL used gun sites.
My first ruger MK 3 Blue 5" (short barrel) is now getting the mag disconnect removed and cleaned...I pay a gunsmith to do this (it has been 5000 rounds since cleaning) great gun
My second MK 3 S/S 7" (long barrel) has already been converted (and longer bolt release and mag release) because I have fitted grips..
The Buckmark belongs to my wife, nice gun but she finds it a bit more ammo sensitive than the Ruger...( I haven't cleaned that in a while, so I don't remember how it is to put back together)
On another note, there are nice 22 revolvers that are fun for target shooting...
even some relatively less expensive ones, that may be the way to go for a starter gun.
Probably a good idea would be to go to a store that has a range and rents guns to see which gun is most comfortable to you.
