i own two swiss rifles and think they are indeed fine rifles,but not my choice for a combat rifle. maybe a little to fine like the german luger for tough combat service.
Perhaps not the best possible for "tough combat service", but I don't think the Swiss were concerned too much about terrain and conditions outside of Switzerland. The Swiss don't need rifles that can fight in the desert or the tropics, and they are VERY familiar with the alpine terrain where they live.
I checked out the Swiss rifles early on, when the cost of the rifle was actually $10 LESS than the cost of the scope mount for the rifle!!
Sorry if you are come late to the game, but if you are, you are going to pay more, and probably get less for it.
The ordinary (cheap) Swiss surplus ammo rivaled other nation's match ammo for quality and accuracy, but its now about all gone...
There's no way on Earth I would pay $750 for a K31, but then I did my dance with them when they cost 1/10th as much (less, actually). Like EVERY other gun that is no longer made, if you want one, then you pay what the people who sell them want.
There is an old joke, about a German and a Swiss general talking either before, or during the blitzkrieg phase of WWII. The German, (fairly accurately) gives the number of Swiss troops, and then says he can put an army with twice that many on the Swiss border, and then sneeringly says "what will your soldiers do then??"
To which, the Swiss general replies,
"Shoot twice, and go home".
While I'm sure the Swiss banking system, and their neutrality, played a part in the political thinking that kept the Nazis from invading, people overlook the military side too often.
Part of the equation that needs to be calculated when deciding to invade and conquer a country is whether or not the benefits will outweigh the estimated cost. Quite simply, unless the Swiss surrendered with out a shot being fired (which simply isn't something the Swiss would do), the cost of TAKING Switzerland far, far, outweighs the possible gains.
The terrain strongly favors defense (I think the largest flat spot in the entire nation is Lake Geneva), the only "national resource" of strategic value is their banking system, something that would be essentially impossible to capture intact and functional unless the Swiss permitted it. Which, of course, they wouldn't.
And the Swiss, alone in Europe, have a centuries long tradition of the citizen soldier, virtually everyone of military service age gets military training, and arms. They keep their basic arms at HOME, with them. And they still do today, and today's basic arm is a select fire weapon (machine gun /assault rifle).
There are a number of small features about the Swiss rifles I don't particularly care for, but you cannot fault the quality of their construction.
