Every gun owner in Canada should consider it their duty to get the restricted licence and own at least one restricted firearm. Get an AR15 if you are not interested in pistols.
The Restricted category exists because these are the guns they would like to ban next, as footsteps along the path to supressing the "gun culture" to the point where they would eventually be able to ban virtually all firearms - as they have done in England and Australia. The only thing stopping them is the thought that they might lose the next election if they piss off enough gun owners.
An MP in a close riding may look at how many Restricted licence holders there are in that riding and compare that number to their margin of victory in the last election. If the numbers are wrong for them then banning handguns and black rifles is not a part of their platform in the next election, and if the numbers are right it is.
