True, and I'm happy to be wrong, but that's what I was told by Elwood Epps and three of the local gun stores in the GVRD... I wanted the Tactical with the threaded barrel, and they told me no-go, they'd only be carrying the VLEH (non-threaded bull barrel). Same on the Takedown with the threaded barrel. I was also looking at a Distributor Exclusive (SS, threaded 16" barrel, and synthetic stock), and was told that model would not be coming to Canada due to the attached flash suppressor, and that the only way I could get one would be for an exporter to remove the flash suppressor and install a thread protector (or some kind of nut) in its place (although the distributor doesn't ship up here anyway).
What that means for the SR-22, FVSR, or TRR-SR, I don't know... Maybe it's a recent thing, or maybe there's some other way around it. I hope I'm wrong, but that's just what I've heard in the last couple weeks on the subject.
