Changes due to the Schengen treaty
The rules laid out above were changed on 1 December 2008 as Switzerland joined the Schengen treaty; and all member countries must adapt some of their laws to a common standard. Following the draft of the Swiss government for the new Waffengesetz (weapons law), these points will change:
Unlawful possession of guns will be punished.
Gun trade among individuals will require a valid weapon acquisition permit:
this is, from a Swiss point of view, a radical restriction that is assumed will undercut private gun trade dramatically.
Every gun must be marked with a registered serial number.
Airsoft guns and imitations of real guns will also be governed by the new law.
Only one weapon may be purchased per weapon acquisition permit:
Presumably, this will dry out the market for relatively cheap used guns, including popular collector's items such as Swiss army revolvers from the late 19th/early 20th century.
Weapons acquired from an individual in the last ten years (which did not require a weapon acquisition permit) have to be registered.
As a central weapons register was politically unfeasible, the authorities hope to get an overview of the market through this registration requirement.
While the above mentioned "free arms" remain exempt from the weapon acquisition permit, the vendor is required to notify the local arms bureau of the sale.
