Private ownership of firearms in Switzerland has fallen by half in the last decade or so, though not as radically as it has in Australia.

From your many responses, here and elsewhere, I'm guessing you don't find actual facts particularly useful. It makes me wonder how you manage with doing police investigations and trial testimony.

Swiss military forces have been dramatically reduced in recent years. In addition, the gun suicide rate was recognised as such a problem that military personnel are now discouraged from keeping guns at home, and prohibited from storing ammunition. In case of governmental need, ammo will be issued only from secure magazines.
 
One result is that gun suicide rates in that country have fallen significantly, likely to be followed  by gun homicide rates, a high proportion of which occurs in domestic violence.

Of course, in the U.S. the NRA has used tools like yourself to generate an "arms race," which is the lesser version of "mutually assured destruction."
