SWISS SCHMIDT RUBIN KARIBINER K31 RIFLE, 7.5x55mm
A superior bolt-action rifle, this rifle is credited by many historians as being a primary reason Hitler did not engage Switzerland in World War II. As the standard-issue infantry weapon for Switzerland’s militia/army, these rifles were issued universally to male citizens of military service age from 1933 through 1958.
A little over half a million of these rifles were manufactured during that period, and the examples for sale now are rifles which were previously issued, and then later replaced with select-fire combat rifles. Having been imported and sold in the United States for many years now, this rifle has become increasingly popular, and the supply of Schmidt Rubin K31 rifles is dwindling fast. The price is rising to reflect that fact, and year by year, the average price of a K31 in good condition has gone up. It remains one of the more desirable military suplus rifles of the period.
The Swiss Schmidt Rubin K31 (Karabiner 1931) is a straight-pull, bolt action rifle chambered in 7.5X55 Swiss, a round which compares closely to the .308 NATO round (7.62×51 NATO.) Military surplus ammunition is frequently loaded with a 174 grain projectile at a bit over 2500 feet per second, though rounds may be loaded from 130 grains (at over 3,000 fps) to 200 grains (2460 fps or more.)
Contrasted to the Springfield, Mossin-Nagant, and Mauser K98 rifles which were contemporary to the Schmidt Rubin K31, all of those rifles used a locking system wherein the bolt is manually rotated by the motion of the bolt handle in an “up and back, forward an down” pattern, whereas the K31 is operated with a straight back and forward motion. This allows faster shooting in combat situations, with a less pronounced arm motion, which the Swiss may have felt was prone to give a soldier’s position away more readily.
In practice, while all of those rifles were really very good in both design and production, the K31 shines particularly in one regard: Accuracy. It is very common for Schmidt Rubin K31 rifles to shoot one MOA (minute of angle, or one-inch groups at one hundred yards, two inch groups at two hundred yards, etc.) exactly as issued, and these groups are commonly obtained using the factory “iron sights” the rifle comes equipped with. None of the other rifles mentioned can make this claim for a majority of issued military surplus rifles.
It is this accuracy that, theoretically, caused Hitler to pause in assessing Switzerland for invasion along with the rest of Europe, and it is this accuracy that makes the Schmidt Rubin K31 a prize among collectors and avid shooters alike.
