I loved firing the Glock 19 - great pistol. In general I've found pistols easier to shoot than revolvers. If personal carry is a requirement, a Glock would get my vote. That said, I think short guns are the better option for home defense. Carbines and/or smaller bore shotguns are the way to go as far as I'm concerned. Easier to keep on target than any revolver or pistol, plus the range to take care of four legged threats as well. And they're cheap.
