There are reports that the G43x and G48 are in stores already, but they can't be sold until 1/21. Nice that Canada's laws were considered in the design and that might be an added sales incentive, though the design specs are probably enough to do that. I'll check out the G48 and at this point, I'm inclined to get one.
I have an in at the largest chain of gunstores in Florida. I will check with their warehouse manager tomorrow to see if they have them.
