There are a couple other Class 3 dealers in WI. Best thing to do is to hit up a gun show. There is usually at least one Class 3 dealer at the Bob and Rocco gun shows. There's one of those in West Bend the weekend of the 23rd of this month.
There's also a gun show in Slinger this coming weekend and one in Cedarburg on the 18. Might try those and see if you can find any Class 3 dealers or at least find someone who knows of them.
This is who we are, what we do.
