ABSTRACT:
An automatic or semi-automatic pistol is made substantially of polymer materials. The pistol includes polymer upper and lower receivers and a polymer barrel attached to the upper receiver. The operating mechanism includes a bolt, block and a hammer, slidably mounted in the fixed upper receiver with the bolt and block and the hammer being separately springloaded. A gas operated link is positioned to rotate the pistol block from a locked to an unlocked position when actuated by gas from a fired cartridge. A gas port extends from the end portion of the barrel to one end portion of the gas operated link to move the link responsive to the gas pressure to thereby unlock the block so that the block, bolt and hammer can be operated by reaction to the gasses still in the weapon barrel. Other features include encasing the entire operating mechanism in an non-movable upper receiver with a removable trigger, and operating handle and having a cutoff switch to change the firing mode from self-loading semi-automatic action to a single shot action, and a counter-torque muzzle cap to counter the torque of the bullet spin, an automatic hammer safety to prevent firing if the action is not fully locked.
