Not necessary. The reason for our limits and their non-limits is quite clear. They don't want any of their jack booted thugs to get hurt when they storm your house in violation of the 4th amendment.
Nothing to do with crime, saving the taxpayer money (LOL) or any other BS reason they put forth.
***The government that would limit law-abiding citizens to some seven bullets to defend their families***
There is a way around that! Load 14 bullets in the magazine! If someone breaks in shoot them 7 times!
When the cops come there will be seven cases on the floor and seven still in the pistol!
Just say you shot your seven and reloaded with the legal limit real fast! ;-D
