I have never owned a handgun before, but i just bought a house and want one for home protection
Ever shot one? Can you hit what you are aiming at, quickly?
A pump shotgun is more easily managed by novices, cheaper, and has power in spades.....
A 20 guage youth model is pretty handy, too.
I don't want to discourage you from getting a hand gun, but a properly fed shotgun would be preferable at this point.... get that first, then get your handgun and develop your shooting skills with it.
As for range fun gun, the Ruger .22/45 gets the most work when we fo shooting. Easter egg hunting is a hoot!
