http://www.patreon.com/ForgottenWeapons The Hamilton was a handgun entered into the Swedish military pistol trials of 1903, where it competed against guns like the Luger and Colt/Browning 1903. The Hamilton was a simply blowback action chambered for 6.5mm Bergmann, although it did have the interesting and unusual feature of a bolt which pivoted on a round path during recoil rather than traveling linearly. The Hamilton's loss in military trials to the Colt 1903 is not particularly surprising, as it was heavy, underpowered, and rather awkward to handle. It never saw commercial sale on any scale, either.
