I did not answer the poll because it was too narrowly formed for me to include my main interests in firearms. You included "black" rifles, and included handguns but few if any rifles as a choise, yet left out rifles in general.
You did not distinguish between centerfire and rimfire, but somehow included blackpowder.
You included Machine Guns - by which I imagine you mean fully automatic weapons and yet left out choices of other actions such as: single shot, bolt action repeater, semi-automatic, O/U, S/S.
You also tried to lump everyone into restricted categories apparently without considering the generalist.
Those poll choices do not fit me. I am more the generalist. I like to keep as many types of firearms as I can keep legally and afford to keep. My largest number of one type of firearm would probably be rimfires in .22lR, but I have many in centerfire too. These included military arms, collectible firearms, hunting firearms, self defense arms/tactical arms, and so forth, all made up of rifles, shotgun and pistols, and a revolver.
All the best,
