I dunno... you’re already comfortable with the little revolver. Is it your only firearm? You hunt or anything and have familiarity with other stuff long or short? If it’s a second gun to date I’d stick with revolver for now. Depending on where you live and what crime is like, I suppose. Move up the ladder into a bigger frame size and chambering. Something like a Ruger GP100 or a S&W L frame. .357 mag & .38 special. Prob 4”. Start with the .38 specials and go up the ladder with loading from there and see if you hit any ‘walls’ in what you’re comfortable and decent at shooting accurately with. Tons of versatility in loading in a gun like those. Not that you shouldn’t get a semi in whatever. I just bought a full sized high cap 9 myself, for some variation and option expansion. I’d just wait and get the semi later, if you like shooting the bigger revo and still feel like you want or need another platform with the benefit of higher capacity.
