where do I take a test to purchase a gun

In store.

You can take the test at Turners or anywhere that sells guns. I also recommend taking a gun safety class. No matter what you know, they will teach you more.

At the store

In-store test

You can take it at the store, but you will have to wait to get the gun.

You can take it there. Please note 10 day waiting period before pick up. Also lines are about 90 minutes right now
