Swissair,
earlier you mentioned using a bunch of trains to get to the gun shop. From the snipped quote, I wonder how did the trip back home go, since anyone with any gun exposure can tell what a gun slip is. Is this a non-issue in urban Switzerland? (I know you guys have lots and lots of firearms).
I had 3 trains to get there and 2 back as it was a different route. I had 20-odd minutes between connections on the way back so I went for a walk around the town centre with our dog, with the rifle in a soft carry case over my shoulder. Didn't feel like I stood out and I wasn't worrying that I might have an issue.
I've done a few cross-country train and bus trips to collect rifles and never had anyone say anything. Whilst travelling by train and making stops at railway stations, I've also made a pre-arranged pick-up of a rifle on the platform, and I've handed over one I've sold.
Always discrete of course, but I never felt like anyone was even looking at what I was carrying.
When I was in the gun shop there was a guy whose grandfather had evidently passed away and left some guns behind which the guy wanted to dispose of. The guy didn't have a car though, so the gun shop guys said they would drive over and collect the guns. If you inherit guns here, you have 6 months to sort out a license (if needed*) or to dispose of them.
* You don't need a license to buy/own ex Swiss military rifles, including repeaters like the K11 or K31 or semi-autos like the Stgw57. I hope I can find a Hämmerli Trainer system at an affordable price one day, and then I'll buy a K31 to use it!
