Not much you can do but wait. Demand he return the gun immediately? More cans of worms open. Sue him? Good luck filing an interstate suit. As for the delays what are getting? Ivory? EVERYBODY is ordering ivory lately ahead of possible legal bans. Sellers may be swamped with orders putting them behind. Maybe he got sick and fell behind. Who knows? I think we've all had this sort of thing happen. You sit it out and be patient. I'm sure he'll get it out as soon as he can. I know you're anxious but contacting him every few days likely won't help.
