Is there any particular reason why .357 SIG is so expensive and scarce in Canada? I mean, I'm not surprised it's less common than 9mm and .40, but it does seem very hard to get. I can get .38 Super more easily around here, and .357 SIG pistols seem to be more common on the shelves than .38 Super these days.
I think dealers are missing a trick not stocking .357 SIG replacement barrels for the common .40 pistols. Definitely the sort of thing you'd end up walking out of a gun show with I think for $200.
