Sorry for the long delay, it's a busy time right now.
Changes? For the moment: not really. A little more paperwork, that's all. The cops like the new law as much as we do and they know that we do not pose any harm, so they will do nothing to make life (for us and them) any harder then necessary. They do the swiss thing, being pragmatic and taking things the easy way.
If I ever get the chance I have to invite the woman from the local firearms office for a beer, she's just great and really helpful, and a real looker, too, besides the fact that she collects guns and shoots. She literally told me to get more suppressors. And who am I to argue with a woman, or the police?
