my last count is that there are roughly 7 automags in Canada that i can account for, of which i have 4 in my collection, all bought from a friend and collector from Indiana, named Don Nixon. he is on the automag sites as "automagking", who had the largest best collection in the States.
the current automag web site to look at is
http://www.automagpistol.com/home.htm
Because of the nature of the gun, prone to damage, and the costs, i have only trusted Don as he does not sell junk, and his units are pristine and most are brand new, and unfired.
american prices would be in the range of $2500 to $4000, factor in 50% on top now because of dollar exchange, import fees, insured shipping, and GST at the border. however, after it lands and if remains pristine, you can sell within canada and recover your investment.
there were about 9000 or less automags ever made, and in the last 35 years, i understand that less than 1000 are worth buying and maybe about 300 units at new unfired top condition
have to reload, so another $500 or so for dies and brass, or form your own from 308. extra factory magazines are $200 u.s.
i have 6 more coming in from Don (diff. calibers, barrel lengths, and a .22 babyautomag)and in the process of contacting Mark at Questar to proceed with the import. Mark has been great and the automags to date has come in fast and without any hitches.
when these come in by early 2009, i will get pictures posted.
so to collect or shoot the automag is not for the faint of heart. the 475 wildey magnum is safe to fire, and you can find one in Canada, i did at a reasonable price of about $1000. aside from these, there is the 44 desert eagle or the 357 coonan (on CGN ee) more suitable for the day to day shooter.
