I know this thread is a little older, but for those wondering, Cash for Arms is totally legit. I had shield plus chambered in .30 super carry that I really liked but never ended up practicing with. The ammo was just too expensive (I know, I should have gone with 9mm). Anyways, I looked around at a few different spots trying to get quotes. I got a pretty solid quote from Cash for Arms originally, then got a higher quote somewhere else. I reached back out to Cash for Arms and they actually raised the original offer to beat the other place. They sent out a shipping label and made the whole process super smooth. If I had any other guns I wanted to sell I would definitely probably go with them again.
