sparhawk, we require your assistance here.
Gunblast.com lists this gun as having a 4.18" barrel which would make it 106.2mm and importable.
The s&w website does not list a 106.2mm barrel for any version of this gun, however.
Please find out from one of the s&w guys what the "official" barrel length is and if it is in-fact shorter than 106mm; please find out if they intend on making one for the canadian market.
I'll see your $450 and raise you $10... Discountgunsales.com (down in Seattle) has them for $419, so it would be nice if it were somewhere around the same price-point. (Note: their web-site lists the barrel as being 4.25, so there are a lot of different lengths being quoted on different sites.)
I'll be watching this thread, as I've been liking the look of this pistol for a while now. Hopefully it makes its way up here soon!
The only barrel length matters is the one listed by S&W.
4.1" = 10.4cm = 104mm = Prohib
