Drove down last sunday with my lady friend to visit her mom and dad in Green Valley (south of Tucson). I took several copies of my C&R license and made the rounds of the gun and pawn shops in the Tucson area. Came away with a couple nice guns.
Bought one at West of the Pecos gun shop. Nice guys to deal with and they had no problem taking my C&R.
The other I bought from Jensen's (both these stores were on Pima). First I had to convince them the gun I wanted to buy was in fact a C&R elegible, but once that was done there was no problem. Apparently it was the first time someone had used a C&R license to buy a gun. Even weirder for them as I was from CA and buying a handgun. They wrote down every bit of information about me they could think of in addition to getting a copy of my C&R and drivers license. But everyone at Jensen's was very nice, polite, and helpful.
I had no problems with any LEO while down there. The only A**hole driver I had issues with was from California!
We all went out into the desert on thursday morning for a hour or so of shooting and then the GF and I had to hit the road to get back.
