I picked up a K31 last this past summer at a small gun show. Fair bluing, super polished bore, good wood, except for a nicely done repair job, supposably done at the Swiss arsenal. $90 and it was mine. Picked up some surplus ammo and Wolf Gold at another show recently, and finally got time to go shoot it. Very pleased. Consistant 2.5" groups at 100 yards, with the piss-poor military sights. Shot around an 8" group at 200, just playin' around. I can't wait to put a scout mount and pistol scope on this thing and really see what it'll do.
