Yeah, that doesn't make sense.
The fact that a gun you bought from someone else didn't meet your standards shouldn't have bothered him at all.
If you were willing to pay his shipping/handling fee to return the gun, he shouldn't have been upset about that either. It's a service he provides and he quoted the price. If he's unhappy, he's the one to blame for offering a service that he doesn't want to perform and/or charging insufficiently for it.
If he blacklisted you for that, I'd say he did you a favor. You might let other folks know who the guy is so they don't get mixed up with him.
