Jeff, we Canadians cannot ship our guns into the USA for gunsmith/stock work unless we have a Form 6 ATF and then we have to bring them in personally.
We have a British gunsmith in Ontario and he is backed up for over a year. My lefty friend with the new 686 will send his gun there when the season is over. We do have LH 680 series stocks for $900.00 each from the Vancouver Beretta importer.
I was looking for a used 682 12 ga sporter on Ellwood Epps (Ontario) website and I noticed one which looked like it had a left hand palm swell, on a pic of the top lever.I bought the gun, fantastic, a custom LH skeet stock, a beautiful piece of walnut.
Had to remove 1" from the 15" LOP, fits like a glove!
