  • Patent number: 7703230
    Abstract: A firearm has a frame, a slide, a striker-type firing pin (“striker”), and a fire control mechanism including a sear to controllably release the striker and a trigger bar for actuating the sear. An automatic positive striker lock safety includes a pin-like safety element biased downwards to normally block the striker. The bottom of the pin is rounded, and cooperates with a rearwards facing, sloped surface on the trigger bar. If striker becomes free to move forward without full rearwards movement of the trigger bar, the pin blocks the striker. However, rearward movement of the trigger bar forces the pin upwards. As the trigger bar reaches its fully rearward position, the pin is moved to unblock the striker, and the sear is actuated for releasing the striker.

  • Patent number: 6796070
    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: 6718680
    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.

  • Patent number: 6698125
    Abstract: The present invention features a firearm safety mechanism with an improved trigger pull, wherein the weight of the safety mechanism is not on the trigger when the hammer is in the “full cock” position. The advancement presented in the present invention serves to separate the trigger from the trigger bar during the period when the trigger is pulled. As a result, the weight of the safety mechanism is not borne by the trigger while the hammer is fully cocked. This is accomplished by providing means for positioning the transfer bar into the extended position free from contact with the trigger. The present invention further features means, dependent upon the trigger, for facilitating the relocation of the transfer bar from its extended position into a retracted position upon release of the trigger subsequent to discharge of the firearm.
