My brother passed a few months ago and I am now trying to help his widow, my sister-in-law, liquidate his collection of firearms. Some of them have large capacity magazines and canisters. The plan is to list these firearms with their mags/cannisters online for purposes of selling them in the continental US. My understanding is some states do not allow shipment to sites within the state of certain magazines and canisters. Please advise me which states so I can include this information in the online listings.
