I have bought numerous and sold numerous guns on Glock Talk, ARFCOM, most FTF transactions and never once been IDed. I ususally do a bill of sale if the gun was purchased new or through a FFL. I don't think it's the standard to get copy of drivers license. I think the standard is what Scotty did, give money receive gun, that is what I do with firearms if I purchased them FTF with someone else.
