Krieghoffs also have a Cape Gun option.

I know where you are coming from with the single trigger idea. Except I am the opposite. I have always used doubles - rifles and shotguns - with two triggers. I simply can't cope with a single trigger and if used a shotgun with a single trigger pull on the trigger guard with for the second shot.

If you're buying a 9,3 and you want a single trigger - go for it.
