Good luck, I think your county is one of the worst in the state for processing. Mich Gun Owners has a couple of different threads tracking time to issue.
Take the time to TRULY learn the law. The states laws are screwy, and even the best CPL instructors get it screwed up.
Here's a couple of questions for your instructor - Can I carry in a school? The legal answer is yes, as long as you open carry with a CPL
How many loaded firearms can I legal carry with my CPL? The answer is as many as you want. I've heard the answer no more than two by so many "experts" it's ridiculous. That answer makes ZERO sense, because their argument is always the license says pistol. Sorry, if that's your argument, then the correct answer is 1
But, further reading of the law states the plural applies to the singular. There's an attorney chomping at the bit waiting for someone, anyone to get charged with multiple weapons to put the argument to bed.
An my favorite, can a magazine separated from the firearm in the same case contain ammo? For some reason many believe it can not. Partially because the DNR says it can not, but they can't write law.
