Those K31's are real sleepers. The world record open site rifle shot was set back in May with one at 2240 yards and the rifle was bone stock. Most turn their nose up at them. Did you check under the butt plate to see if the tag with the original Swiss issuees' information is under it? All the ones I have, have had them. Some new owners have found their originals and contacted them. They make for some interesting stories. I'm partial to Sigs as well. For those that believe a 9mm can't be a good target gun, have never shot a Sig 210. I have a couple that are on par with some of my favorite Bullseye target pistols that I've used in competition. Both made in the 50's, they keep up with my S&W 52 and Colt mid-range .38 Special target guns. The Clark long heavy slide .38 Special is another story.
I did check under the buttplate, but there wasn't a tag. My best guess is that this rifle was never issued and was an armory gun. It's in very good condition, and doesn't bear the marks of a long wet alpine patrol, because Swiss packs had straps to secure the rifle, and those straps would retain water and damage the end of the butt and somewhere up front. In fact mine only has superficial dents and dings. Another indicator is that the front sight has multiple windage marks. The Swiss manual called for unit gunsmiths to zero the windage and then do a little hashmark in the metal. The manual specifically states that when that is done multiple times the sight is worthless and needs to be replaced, a scenario most likely to happen if multiple people have had the gun, and mine has multiple hashes. Thankfully the one that it was at currently is the correct one.
And this one isn't a K31. This is a K1911 Carbine, which looks similar on the exterior, having the same overall length but a shorter barrel. I plan on getting a K31 too in the future, but they weren't available when I got this one. One thing that still shocks me is how light the trigger is. I looked into it and it seems that it has about a 2.8 pound pull, and it is clean as can be. It has a long takeup, and the shape is strange, but neither of them makes it less usable. If anything they make it more usable than a more modern shape. The bolt is also very smooth, though it does take a good stout yank on the bolt to get it open. All in all, very good for a rifle made in 1916.
And I wish I had a P210. What I do have is a P6. I really like it, though I think I may need to have it seen to, because it keeps getting this one malfunction where it pops a round straight up out of the magazine. I think on one occasion I popped in a new mag and a full cartridge flew out the ejection port the moment I did. At other times it has done that and gotten the brand new round stuck between the barrel and the breechblock.
