The rifle came with one magazine numbered to the gun.

Although the magazine extends about an inch below the rifle, it is nicely contoured with rounded edges and not prone to snagging or causing discomfort. The easily detachable magazine is held in place on the right side by a spring latch to a trigger guard, and the bottom metal is stamped from heavy-gauge sheet metal. Very complex for a single-use item, these chargers were never used in anger, and they’re often found in nice condition-with new ones made of plastic available from Numrich or Northridge International. The follower of the six-shot magazine holds the bolt open after the last shot, and it’s recharged from the top singly or by a strange-looking, fragile six-shot charger made of tin and papier-mâché. The receiver sight featured a ladder allowing sighted fire out to 1,500 meters. A muzzle protector (in background) snaps over the sight-protecting the crown and blocking the sight picture so shooters wouldn’t fire the rifle with it in place. The front sight is windage adjustable by driving it up or back in an angled dovetail. These rifles will often shoot much better with the addition of aperture sights. at 100 yards with surplus GP 11 ball ammunition. On a good day, I can hold about 2.5 m.o.a. Straight-pull mechanisms usually require more effort than turn-bolt designs, and the Swiss bolt has a comfortable aluminum “T” handle to pull. While other straight pulls have conventional bolt knobs, the Swiss early on thought more uniquely. The K31 is as fast or faster to fire than the Lee Enfield, lacking only a commensurate payload. While the Allies were hot on the Axis heels, the Swiss must have felt like a big, fat steak in front of a hungry wolf, but they did have a citizenry ready to muster armed with one of the best battle rifles of the era. Yet the threats were real, and the K31 was kept at the ready all during World War II, when Switzerland was surrounded by German-occupied Europe and Fascist Italy. Switzerland has maintained peace with its neighbors for centuries, and there are few tales associated with the small arms beyond thoughtful design. Normally, here I would regale you with thrilling accounts of actions involving these rifles. Citizen-soldiers issued the K31 cared for them very well, and they are rarely found out of order or heavily worn. The K31 was beautifully finished inside and out and is usually found in very nice condition with excellent barrels still full of life. One of the all-time great straight-pull rifles is the Swiss K31 in 7.5x55.
