This is true. However and this is just a few of the conditions from Swiss gun legislation:
- all automatic weapons banned.
- all semi-automatic weapons banned.
- all people must get a Weapons Purchasing Permit (and pass a criminal background and psychological test).
- to carry a gun on the street requires a Weapons Carrying Permit (they are normally only given to security and the police).
- all private weapons must be stored in a locked box.
- until 2007, government issued ammunition was kept in sealed boxes which was a criminal offence to open. Now ammunition is not kept at civilian premises.
SR 514.541 Verordnung ber Waffen, Waffenzubehr und Munition
SR 514.54 Bundesgesetz vom 20. Juni 1997 ber Waffen, Waffenzubehr und Munition (Waffengesetz, WG) (there is a PDF on this page which is quite extensive)
If America tried to enact similar legislation, all automatic and semi-automatic weapons would have to be seized immediately, as would virtually all ammunition, locked boxes would be required in people's houses that had guns and most people would be disallowed from carrying a gun outside.
It would however be closer to the actual wording of the second amendment:
A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed.
Switzerland probably has the most highly regulated rules for gun ownership in the Western World. This point is almost always ignored by pro-gun people in the United States.
