The slide is probably Brazilian, at least the one I got from them a while back is. Mine is straight, square, and little used, but pretty roughly machined. I have a takeoff SA barrel in it and use it as a .22-45 conversion on my Ace .22 to try odd sights that I don't want to alter a working gun for yet.
The small parts may be Brazilian, too. If they couldn't get a license to import guns, they may have scrapped the receivers and brought in the rest as spare parts. Or they might be any combination of cheap copy, rejects, and surplus. Who knows?
Call 'em up and see if they know AND will tell you.
