Yeah, kinda assumed that by what I've heard before.
Did you mean regulation in Germany, Mia?
Well, to own any weapon you need to get a license (like a driver's license for guns), and for every single weapon you buy you need a weapon's owner card. Every weapon that is, or could easily be turned into an automatic weapon, is forbidden.
Most people only get a license to own that weapon and use it in closed shooting ranges. Only for special purposes (security person, highly threatened person) you may carry your weapon outside the shooting range or your closed-off private ground. Many calibers are not freely accessible and for many you need to write an application with a detailed explanation as to why you want that weapon, and normally you only get the license for those weapons if you're participating in special sport shooting disciplines.
As a collector most weapons are only allowed if they can't be fired anymore, or you may only store them inaccessible.
Hunters may also carry their weapon in the area where they hunt, outside of that only unloaded and secured, of course, and only if they couldn't place it somewhere as far as I know.
And last, before you can even think of purchasing a weapon you have to have installed a classified treasure and show evidence of it, or have documentation that you store your weapon in the shooting club facilities.
Should you be caught carrying your weapon outside you'll lose your license, though I'm not sure how it is regulated if you don't have ammunition with you. But if I'm not mistaken that doesn't matter.
To my knowledge they don't control it, but should it somehow get public that you don't store your guns appropriately you will be fined as well, and might lose your license.
