Yes they are available in Canuckistan. Questar and other dealers have brought them in and they are restricted.
I have one that I added to a derringer collection. Nice little gun, but for us Canuckistanians, it is nothing more than a novelty. Would make a great pocket gun when out in the bush, but allas not in our country.
For what we can use them for, they are grossly overpriced selling new for around the $800+ mark, and used anywhere from $650 to over 900!
