that's the case for my glock, my ar-15, and my shotgun. i won't lie and pretend that i know everything about guns, but it's a pattern i've noticed.    op is talking in terms of germany, where laws are stricter and i don't think you can privately transfer ownership of firearms. i also thought that you can be subject to an inspection of your guns in germany/get in trouble for not being able to produce them, but maybe i'm thinking of another country.
