Another problem to consider if how are you going to send the package once all the paperwork is finally completed? Last I heard none of the major couriers- UPS, Fed Ex, Purolator, etc. have permits in place to transport the guns into the USA. As far as I know sending handguns in the mail by using Canada Post/ USPS is forbidden. Last I heard Air Canada Cargo was licenced to transport firearms into the USA but I was told that they're charging an outrageous amount to deliver restricted and prohibited firearms. If anyone can relate their experiences I'm all ears as I'd love to send a few prohibs south of the border.
