I have never heard of any limit on the number of magazines you can carry. Though maybe after reading your question the hoplophobes will try passing some. But I’m sure you are going to get an awful lot of unwanted attention from regular people and LEOs if you walk around wrapped in loaded magazines.
FYI, you are likely to get some grief on the gun forums for calling magazines clips. Unless you are referring to stripper clips for something like an old Enfield rifle? Or the M1 rifle clip pictured below by @PossumSlayer1
In Illinois, the only place you need to worry about capacity limits is Chicago/Cook County area. The rest of the state is free. Carry as many magazines, of whatever capacity floats your boat. If you have an Illinois carry license.
I couldn’t re-find the reference I once read, but I think there’s an overall limit to how many rounds you can legally bring into California. Doesn’t matter from a reciprocity perspective though, because California doesn’t offer any reciprocity.
7 points for for naming the states in alphabetical order ( unless a cheezy copy & paste job - then 4 points for texting skill) minus 2 points for leaving less space between Wisconsin & Wyoming. & Welcome…
I’m surprised you didn’t ask how many 17-round magazines you can carry.
10-round mags are for behind the iron curtain. And even in Kalifornia, I never heard of restrictions on number of mags. If any, it would be self-imposed due to weight, considering how people are very particular about how many ounces their conceal carry weapons weigh.
I have a quick draw waistline pouch (fanny pack worn in front) for my 9mm and 4 -10 round clips because my 15 round clips don’t fit in the quick draw pouch. Those 3 are in the big pocket on the inside of the belt.
So now I am carrying 95 rounds which are good for a 5-10 minute firefight…
I only carry in Reciprocal states but still, I need to avoid carrying too many rounds if there is such a restriction.
