I'm looking for a ccw wheel gun for myself and for my gf.

I currently carry a full size sp2022 and I'm looking to replace it with a .357. Seeing as I've never owned a revolver I'm looking for some advice on what to look for and what to expect. My gf is getting her license soon is dead set on a revolver so im,looking for something for her as well via /r/CCW http://ift.tt/2x3AuiY
