  • Publication number: 20030145504
    Abstract: A locking mechanism is provided for a semi-automatic handgun. The locking mechanism is readily retrofitted onto the back of the handle frame of a used handgun. The locking mechanism includes a pair of guide rails fixedly attached to the back of the handle frame and a movable locking bar slidably carried between the guide rails. The locking bar is movable between two positions. The first is an unlocked position in which the handgun may be fired. The movable locking bar can be readily moved upwardly to a second locked position in which it interferes with the forward motion of the drawbar. Since the drawbar cannot move forward, the handgun cannot be fired, the slide cannot be actuated and the user is unable to chamber a round. The locking bar is unlocked by a key actuated locking cylinder carried in the bottom of the movable locking bar. The user can quickly lock the gun by simply pushing upwardly on the movable locking bar.

  • Patent number: 6588136
    Abstract: A fire control system with a decocking lever that operates to decock the hammer and also as a safety. The fire control system also has a magazine safety to complement the decocking lever's dual functions. The magazine safety is in the “safety on” position when a magazine is not fully seated in the magazine well and in the “safety off” position when the magazine is fully seated. In one embodiment, rotating the decocking lever by lifting one of the thumb tabs applies the safety if the hammer is cocked and rotating the decocking lever in the other direction causes the sear to release the hammer but catch it before it reaches the firing pin. In an alternate embodiment, the decocking lever can be used as a safety regardless of whether the hammer is cocked or not. Further rotation lower a cocked hammer.

  • Patent number: 6460282
    Abstract: My invention is a new and improved hammer mechanism which reduces the strength of the hammer mainspring without also reducing the hammer's strike force. My invention comprises a link mechanism integrally assembled to the hammer of a firearm. The link mechanism moves at a positive velocity relative to the hammer as the hammer itself moves from the “cocked” position to the striking position. Both the hammer and the link mechanism are biased into the striking position by the hammer mainspring with a section of the link mechanism protruding from the front surface of the hammer and impacting the firing element of the firearm or primer. The link mechanism thus impacts the firing element or primer at a velocity and force roughly equal to the aggregate velocities and forces of the hammer and the link mechanism.

  • Publication number: 20020020100
    Abstract: A semiautomatic handgun having multiple safeties includes a body made in two halves and a slide which can move lengthwise on a pair of rails. The hammer is cocked by rearward movement of the slide. The trigger, which has purely translation motion, is blocked from behind except when the user is wearing a special magnetic ring on his trigger finger. A decocker mechanism pushes the firing pin forward and slides the sear back, and prevents release of the hammer until the firing pin is blocked. The firing pin is normally blocked by a cup, which prevents the firing pin from moving forward if the gun is dropped. The cup is moved to an inactive position by a release lever only when the trigger is pulled. A safety lock, which is preferably operated by a special tool, prevents the transfer bar from moving. The firing pin block lever is locked in a downward position when the safety is activated. A hammer block bar prevents the hammer from moving when the safety is on.
