ABSTRACT:
A safety mechanism for use with a firearm having a hammer wherein the hammer has an elongated, vertically extending recess formed therein, a transfer bar traveling within that elongated recess between an extended position and a retracted position. When the transfer bar is in the extended position, the bar is interposed between the hammer and the firing pin allowing discharge of a cartridge within the chamber. When the transfer bar is in the retracted position, a portion of the recess is exposed. The exposed recess is larger than the portion of the firing pin which protrudes from the receiver. Thus, inadvertent firing is prevented as the hammer cannot contact the firing pin. A transfer bar carrier pin located on the hand assembly initially cooperates with the trigger cam and the transfer bar to elevate the bar into the extended position. The weight of the safety mechanism is, therefore, not borne by the trigger, when the hammer is in the full cock position, resulting in a lighter and more accurate trigger pull. After the trigger has been fully actuated, the transfer bar carrier drops with the hand mechanism and a cam on the trigger maintains the transfer bar in the extended position. The trigger must remain in the fully actuated position until the hammer and transfer bar impact the firing pin. Premature release of the trigger will allow the transfer bar to drop and the firing pin will merely enter the recess in the hammer without contacting the hammer.
