I would say it is Pro Gun. Hunting is definitely a big deal so when I was a kid I grew up around guns like many of my friends and it was no big deal. The further North you go the hunting culture becomes even more evident. When we were kids my cousins who lived near West Branch would have their schools closed on opening day of deer season every year because so many people would go hunting with their Dad. I have a cottage up in Grayling and there is a private range that I use for target shooting. I kid you not, 50 yards from the range is Preschool and Day Care Center. It is no big deal to them.
As for everything outside of hunting I look at it this way. I have every firearm I currently want. You can get an NFA item if you want one. There are plenty of retailers that carry a good inventory. There isn't a waiting period or mag restrictions. The couple of times I have been pulled over and showed my CPL it was a non-issue. We have over 500,000 CPL holders in the State.
Are there States that have fewer laws, yes. There are also States that have an assault weapons ban, mag capacity limits, and "may issue" CPLs. One other thing to think about is this. States like Colorado were conservative and pro gun back in the day. Then there was the influx of Liberals from California moving to Denver and they started changing the laws. Pro Gun cities like Austin and Nashville are getting tons of anti-gun Millennials moving there and they vote. The one thing about Michigan is most of the people you meet here were born and raised here their entire life. The people you meet on this board like myself are willing to fight for our rights and wont give them up easily. Put all of that together and I say we are a Pro Gun State.
