Hey everyone. I have a quick question. I am in talks with a gentleman about trading a decent laptop for a Springfield XD and a Marlin Model 66. I have never purchased privately from a stranger (only from trusted friends/family so all I have ever done paperwork wise was a bill of sale with the make/model/seriel number/name/date and us both signing it). My question is what all should I have included in the bill of sale paperwork? Any other things I need to do/be weary of (I do plan to ask him if he has a permit as I prefer to deal with license holders)?
