Thanks,
I am an American and purchased/acquired them there in the US. I could tell you about the process of importing in Denmark and exporting out of the US, and all the applicable US State Dept paperwork. Also I just moved here a couple years ago with my wife (she is Danish) and my daughter, so I haven't bought one here YET. But it won't be long. I ll let you know.
The ammunition is for sale at the store at the gun club that I got to. I am allowed to reload if I want to.
What sort of activities can you use your M-27 for in Denmark. Are those activities confined to the gun club?
