Maybe future gun designs will include a EURion[1] mark? The problem is you're building a utility item that can be constructed in literally an infinite number of ways, and defining some sort of 'Is this a gun?' test seems to me like verging on hard AI. Of course, simple rules like 'this is 85% the same as that knockoff AK47 pattern distributed in the "Anarchists 3D Printing Handbook"' will probably catch the dumb ones.
