Yet another philosopher here guys, "quite clear & criminal code" you sir must be a lawyer cause this here country bunkin could swear that "quite clear" is pretty muddy when it comes to shotguns. I'm sure CANAM will come around shortly and for the BILLIONTH time post the shotgun regs for your city slickers to translate for us.
And to throw another fly in the ointment I would like to bring to your attention that you CAN put a pistol grip on your 12.5 inch shotty and it WILL remain non-restricted, but if you want to leave it on for more than 29 days you have to report it to the CFO so they re-classify it as a restricted, then you will love this, once its a restricted it can't be reclassified as a non-restricted (I'z Thinks). The point I'm trying to make is that simply making it shorter than 660 mm's temporarily doesn't make it a restricted, so all you "FACT" commanders are quite wrong
At this point if I was a rapper in a rap battle I would drop my microphone spread my hands and say "school up before you step up, suuuunnnn"
