I know enough to know that I know enough to land my sorry butt in jail if I even look across the line, nevermind actually crossing it.
For my part, I'll just leave import marks alone and look for a frame that's clean. No worries that way. Or maybe just sacrifice one of my non-collectable Lugers to the "Baby Luger Project".
I wouldn't have thought the question would have been so cloudy. But it does involve the goverment so I should have known better...
