The other thing too is just because it's on the Polys list isn't necessarily a guarantee that the government will ban it. There is one particular model that has always been on the Polys list and has not been banned yet and I personally doubt it will be. Also remember that if / when PP takes the helm of the CPC, there is a very strong likelihood that the Liberals won't survive another election. Once the government changes (which history tells us it will eventually, and I think sooner rather than later), the Polys voice will be rendered moot and irrelevant.
Don't get the fear of what may happen dictate what you do. I would love to be in a financial position to be able to afford an APC223...but I have quite enjoyed target shooting with the vast majority of my NR firearms which are on the Polys hit list...I have bought the vast majority of them knowing they are on the hitlist, but ain't gonna live life with a "what if the government does this?" attitude. Enjoy the freedoms while you have it...
