I think that, with the exception of our lack of CCW permits, Wisconsin is a great state for guns.
We don't need any kind of permits to buy or sell, unlike many other states.
No limits on the number of guns you can buy or the frequency with which you buy them.
Full-auto's, suppressors, AOW's and other NFA stuff is fine (depending upon the sheriff).
No waiting period on long guns, 48 hours on handguns (we'll get rid of that eventually).
Range protection act so whining anti's can't shut down existing ranges.
Preemption bill prevents cities from enacting their own gun laws.
One of the largest ratios of NRA members to gun owners in general of any state in the country.
Anti-gunners haven't been able to get a bill passed for as long as I can remember. (Was probably the 48 hour waiting period, and I forget when that happened).
RKBA amendment to the state constitution is changing things as we speak.
