Smuggling is highly not recommended, a local member recently attempted to do so and was caught and severely fined. As it stands there is no real way to reacquire it legally at this point in time and ordering from outside of Canada is essentially useless for the same reasons as why you cannot bring it over the border.
There are a few online retailers in Canada that may carry your item, and I believe I saw a few KSC USP's for sale in this websites buy in sell area. However you require this websites age verification to view and buy from that area of the forum.
