All right. Here's my take on why the OP is in the right. Feel free to argue with my logic on this one. 1) OP went through proper channels (4473, etc) to rifle transferred back into HIS possession prior to the sale, or any deal being struck outside the shop. 2) The dealer's commission isn't to stick a tag on the gun and make room for it in the shop; it's to make a sale. If he can't or won't close the deal, he doesn't get commission. 3) While on the premises of the gun shop, the transaction did not take place in the shop, nor did it happen while the gun was still on display in the shop. Those facts alone lead me to believe that the dealer didn't have a hand in anything except making the eventual buyer aware the gun was available. If that deserves commission, my butt's going into Walmart to get my cut for letting people know when something's on sale. Come to think of it, I'm going to every place I've recommended or referred someone to for my share of the profits. Who's with me? Snarkiness aside, from a more speculative standpoint, the dealer was caught red-handed before trying to rip the OP off, by making a trade on a consignment gun, then selling the trade-in for additional profit. Were I in the dealer's shoes, I'd notify the owner of the consignment gun of the offer, then offer to A) facilitate the trade for a modest fee or B) buy the consignment gun off the guy, trade it, and resell the trade-in at a fair price for the dealer and the owner of the consignment gun. The second option is certainly the less viable, but if the seller can agree to a reasonable amount, and all parties agreed, then go with it.
