I was kind of dreading this announcement, as there were rumours of a Glock carbine.
If that happened, I'm pretty sure that the next thing that would have happened up here in Canada, would be that the RCMP lab would immediately declare all Glock magazines to be "dual purpose", designed for the carbine, and thereafter be restricted to 5 rounds, thus making every 10 round Glock magazine in Canada a prohibited device, and every owner an instant criminal.
They already performed this sleight of hand space and time bending time travel a couple of times.
First, when S&W brought out the pistol version of the M&P 15-22, a couple of years after the carbine, and the 25 round .22 magazines had to be limited to 10, because they were obviously originally designed for the handgun version.
Second, when Ruger brought out the Challenger, as they deemed that the Ruger 25 round magazine, that came out decades before the Challenger, was somehow originally designed for a handgun, and was thereby restricted to 10 rounds.
They will always restrict the magazine to its smallest capacity, so unrestricted capacity .22 rifle magazines become 10 round any calibre handgun magazines, and 10 round handgun magazines become 5 round centerfire long gun magazines.
Having said that, the fact that it is the size of a Glock 19, immediately makes it a prohibited handgun, as the barrel is a couple of mm short.
So we will have to wait until either there are longer/threaded aftermarket barrels that can be fitted prior to import, or Glock themselves deems it viable to produce a "Canadian" version, like they did with the 19 Gen4. I won't hold my breath over the latter, as we have yet to see either a 19 Gen5 or 45 up here without aftermarket barrels brought in by a "grey-market" importer, as Glock wants to sell all their 19 Gen4s and their "hey, we made this just for Canada" 48s first.
I guess I will get to shoot them at SHOT next month though, so there is that.
