"Devious" is correct, I own a Custom Sport, and I believe the only difference is the threaded barrel...last time I checked suppressors were not available in Canada (Ontario anyway), so not sure of the benefit over the non-threaded barrel. price also looks right. purchasing from the US gets you a cheaper gun initially, but processing charges/fees and shipping bring the price a lot closer to what we pay here...not always, individual prices vary, and while I have purchased and imported from the US, its not always worth it
