Excellent customer service there. Especially important since you are new to firearms. I would have hated to see one bad experience turn you away from the hobby. Sounds like CDNN took good care of you. Yeah, you mostly get what you pay for with firearms.
There's some really experienced guys on this board. I'm fairly new to the hobby myself and got sucked in hard core, but this board has helped me learn an awful lot.
I usually get input from the guys here before I go buy something, then I hold it in my hand to see if it feels right.
I'll let one of the senior members tell you to take a safety course. It's coming and you should.
Congrats on getting this resolved. What guns did you end up getting instead?
