So, after reading a LOT of glowing reviews and wanting to honor my heritage, I purchased a Swiss K-31 at the last gun show. I'm pretty sure I got the only one in the entire show WITH the Troop ID Tag under the butt plate. The previous owner of my rifle was a Dragoon... HOW COOL IS THAT?!?!? His name was Roger Gerrier. Actually, through a bit of research, I found that the Swiss were the last in Europe to use an actual (NOT ceremonial) mounted cavalry. They used it well into the '70's.
Anyway, the rifle is in decent (not great) shape. It has about 60% bluing, and the stock is beat up in a few places (probably from the saddle scabbard), but the bore, chamber, and action are perfect. Everything about the design of this rifle is genius... From the straight-pull bolt to the two-stage trigger, to the front sight that is windage adjustable through moving it toward or away from the muzzle in a diagonal dovetail.
The straight-pull action functioned like a champ. It fed my surplus GP11 rounds (actually, its predecessor was the inspiration for the U.S. 30-06 cartridge) perfectly. It shot them even better. It has a steel butt plate, and the recoil was significant, a good thump somewhere between a .308 and a 30-06. It however was not painful, at least not until the last group I shot (rounds 22-24), when the bruise on my shoulder had a chance to swell up a bit.
Now, I am NOT a marksman. I shoot for the fun of it. I'll tell ya one thing, though, this rifle shoots a LOT better than I do. By the time I left the range, once I settled in, I was consistently shooting 1 1/2 to 2" groups at 100 yards. Keep in mind, this is an open-sighted, military surplus rifle that was built in 1944. 1 1/2 to 2" groups, CONSISTENTLY at 100 yards. Actually, my best group was my first. I shot a 1 1/4" group with the first three rounds I shot. After that, I shot a couple of 3 and 4" groups, which is still pretty darn good, before I got settled in. I am right-handed, but I have a quite painful torn rotator cuff in my right shoulder. So, you guessed it, I was even shooting left-handed. The rifle was shooting about 5 - 6" to the right, but I didn't bring any means to adjust the front sight (DUH!), and I was just shooting for groups anyway. I did adjust it a bit later, at home.
The gun shot like it was born to shoot. It ran (not so ironically) like a Swiss watch. It is, without question, the most accurate milsurp rifle I've ever shot. In fact, it is easily the most accurate open-sighted rifle I've ever shot. MAN, I LOVE THIS GUN!!!
