Sunngård Automatic Pistol: 50 Rounds in 1909

Doing the classic inventor thing, Sunngård figured out a solution to the problem – a two-part solution, in fact. The first part of his solution was to use a big magazine and a small cartridge, to maximize magazine capacity. The second part of his solution was to store a spare magazine right in the magazine well of the pistol for immediate use. The grip of the pistol is long enough front-to-back to store two identical magazines. The front magazine sits higher than the rear one, and the boltface on the slide feeds rounds from the front magazine into the chamber. Once the front magazine is empty, the shooter ejects it, and need only slide the rear magazine into the front position (and rack the slide) to continue shooting. There is a misconception that the pistol will fire automatically from both magazines in succession, but this is not true. In addition to having the handy spare available, Sunngard designed the magazines to hold no fewer than 25 cartridges each (in the more common 6.5mm chambering). This gave the pistol a total of 50 rounds stored on-board, which was a major point in Sunngard’s marketing. The 6.5mm cartridge designed for the pistol had a 23mm overall length, and used a 19mm case. The projectile was a scant 28.5 grains (1.85 gram), and Sunngard claimed a muzzle velocity of just under 2000 ft/s (600 m/s) – which is almost certainly an exaggeration. There was also an 8mm version of the pistol made in much smaller numbers, which fired an equally light projectile (29gr / 1.88g), and may have gotten closer to the claimed velocity (magazines for the 8mm version hel
