The airsoft pistol you mentioned would indeed be illegal to import and acquire in Canada. Airsoft guns are currently classified as replica firearms, and replica firearms are a subset of prohibited devices. As a real steel shooter, you're probably aware that there are no PAL or RPAL (or "P"-PAL) permission for prohibited devices.
Orange tip has no legal bearing in Canada. It's a silly, American thing.
And you're right, it is stupid
. You won't get any arguments from us.
