I don't know if this is in the right place, but I'll ask anyway.

I just got back from Gander after some disappointing news. I've been a CO resident for a month, just moved here from New York, and wanted to purchase my first handgun. There was a good deal on a Sig P226, very used (full of character!) but a perfect first handgun in my opinion. As we started the paper work, the guy at the counter was looking at my license and said, "Oh, this was just issued last month. Have you been a resident for 90 days?" and I said no, I just moved a month ago. He said that the buyer needs to be a resident of CO for 90 days before purchasing (he didn't say all firearms, or handgun specific).

I've never heard that before, and went out a couple days after moving to get my license for the exact reason to purchase a handgun.

I just got off the phone with a helpful guy at The Shootist, and he said as long as I have a CO license there's no issue.

So...is this some bullshit Gander policy or a federal/state law?
