There are basically 2 potential sources of M&P factory barrels in Canada, and they either don't have one or can't sell you one. Murray Charlton (last I talked didn't have one, as S&W haven't shipped any of the parts he ordered) and Wortners, who likely won't sell you one (if they have one) because it might be needed for warranty, and they won't be able to get another. Smith has really dropped the ball on it's parts shipments, as in they aren't shipping ANY. Even their warranty centres (both mentioned above) can't get parts. Buy a Storm Lake, from what I've seen they're available, and they're better quality.
