Wisconsin has had concealed carry since 2011. The permits last for 5 years before you have to renew. I had to renew my permit for the first time two years ago. It was painless online with the obligatory government fees. I had the new permit in hand in less than a week.
Have you renewed? How was the renewal experience?
Not sure how to renew your permit you can find details on our reciprocity map: www.uscca.com/laws
