If I suspected a gun being hot, I would make the call to the local PD. Even when I purchase a gun legally from another individual, besides writing down the model and serifal number of the gun, I write downthe seller'sname and address off his license, phone number, and we both sign it. Make a copy for him and I keep the original in my safe. That way if I happen to trade it later and it is hot, at least I have a leg to stand on (I hope).
