needs more ammo
My dad was a big proponent of 22LR for home defense - pop pop pop - you put 3 rounds in the intruder before they know they've been shot. etc etc... But I don't think too many people are going to find themselves thinking "Should I get this Ruger 9mm PC Carbine or should I get this Ruger 10/22 ? Hmmmm, which one should I buy ?"
This poll is focused on centerfire auto loading pistol cartridges, that's for sure.
