A Ruger 10-22 and about 20 or so 30 round magazines.
Hi Point carbines just keep on working, and they are inexpensive, spit 9mm or 40 cal or .45 ACP. Only drawback is magazine capacity, but you can buy lots of factory mags at a reasonable price and the rounds hit harder than a .22lR. As to handguns ... well, .45 ACP out of a 1911 is hard to beat, and there are twenty round mags for 1911s now. Personally, I depend upon the little M1 Carbine to compliment the higher caliber rifles. I can’t see all that well out past 100 yards anyway, so the M1 is all I really need for a personal defense rifle. Of course I load it with hollowpoint ammo.
