Folks I've talked t,o have zero interest in complying with this new regulation. Seriously, are they going to throw hundreds of thousands of people in federal jail? Out of all those, I'm sure there would be some physical resistance too.
Look, this is all just more stupidity under an already stupid law (that we all seem to accept for some reason) -- got a 16" barrel? You're good. Got a 15.5" barrel? Then you pay $200, wait 8 months for the crown to give you permission, submit forms/fingerprints/photo, deep engrave your gun, register it with the government, possibly set up a trust, and look for complications/barriers if you want to transfer it or if you die. F@%$ that.
