Unless that's something new that was added in the last ten years, since I needed a purchase permit, the only test was can you sign your name.
I bought my first handgun last year, and had to get the purchase permit. It was no big deal, just a minor inconvenience. The lady at the police station said that nobody fails the test...but they do go over any incorrect answers with you. They’ve since dropped the requirement to take the gun back to the police for inspection.
The good news is that these are being heard by natural resources. That's the good committee. Judiciary is the bad one. We've been working on the state laws for years trying to turn back 80 years of bad laws. We're moving in the right direction.
Hopefully Dillon puts these up for a vote. He will if it's politically expedient. It might be after the August primary. He's running for governor.
I had to take the test a couple of years, before I received a CPL. But, one of the questions was worded strange, and the Sheriff marked my answer as wrong. After I explained their mistake, they marked it correct.
So much for the “test”.
