Then so is the RCMP.
Check the notes to FRN 139668 (That's the Dlask shorty) - I believe this would apply here too:
"this firearm is normally Non-Restricted unless affected by the following conditions:1) by combining a barrel from a licensed firearms manufacturer that is less than 406mm (16.0") in length and a receiver/frame fitted with a pistol grip only, this firearm may be deemed a "handgun" and therefore "RESTRICTED" under the definition of "restricted firearm" in Part III/Firearms and Other Weapons of Section 84 (1) (a) of theCriminal Code of Canada."
Yes, the FRT is not law, and you can do as you see fit. But this is not the hill _I'm_ willing to die on so I won't do that or suggest to anyone that they do. In fact I think I'll sell off the pistol grip I have for the Dlask shorty just so it's nowhere near the gun...
And TI have said themselves that they had this gun set up with a stock _on purpose_... Yeah, post 24 - that's why there's a _minimally_ functional stock and pistol grip is not happening.
