Abstract
An internal firing pin safety mechanism for a pistol, for example an M1911 80-Series pistol, which is activated by the beaver tail, rather than the trigger. The mechanism's constituents are comprised of a beaver tail, which engages a beaver tail lever when gripped, which in turn engages a plunger lever. The plunger lever then pushes up a firing pin block that has a concave opening, which allows the firing pin to pass through and strike the pistol's chamber.
Claims
1. A firing pin safety apparatus for an M1911 80-Series pistol comprising a firing pin, a grip portion having an outwardly extended portion, a grip lever having an elongated protruding portion, and a plunger lever having a firing pin block and a notch to movably engage with the protruding portion of the grip lever, wherein in a locking position, an angular movement in a counterclockwise manner of the plunger lever triggers an upward movement of the firing pin block to engage with the firing pin and prevent an axial movement thereof.
2. The firing pin safety apparatus for an M1911 80-Series pistol of claim 1, wherein in an unlocking position, an angular movement in a clockwise manner of the plunger lever triggers a downward movement of the firing pin block to disengage with the firing pin and allow an axial movement thereof.

(5) FIG. 5 is an illustration of the internal firing pin safety mechanism within the context of a pistol.
DETAILED DESCRIPTION OF DRAWINGS
(6) FIG. 1 is a side view of the internal safety apparatus. The entire mechanism consists of five main components. When the user grips the firearm in a natural fashion, the beaver tail (11) will be pushed inwards. This movement will activate the beaver tail lever (14) by imparting a torque on to it, causing it to rotate in a clockwise (from the point of view of FIG. 1) fashion. As a result, the beaver tail lever (14) will connect with the plunger lever (13) and impart a torque on to it. This will cause the plunger lever (13) to rotate in a manner opposite to that of the trigger bar lever (counterclockwise from the point of view of FIG. 1). The angular momentum of the plunger lever (13) will cause it to make a connection with the firing pin block (12). The plunger lever (13) will impart a force directed in an upward fashion to the firing pin block (12). This will cause the firing pin block (12) to rise upwards, revealing an opening through which the firing pin (10) can pass through and strike the firearm's chamber. It can be obtained from FIG. 1 that the firing pin block (12) is in said upward position, and the internal safety mechanism is therefore disengaged and the firing pin (10) is allowed to strike the chamber.
(7) FIGS. 2 & 3 are rear views of the internal safety mechanism when the safety is engaged and disengaged, respectively. In FIG. 2 the firing pin block (12) is in its downward position, and the firing pin (10) is therefore blocked from striking the chamber. In FIG. 3, however, the firing pin block (12) is in the upward position, having been acted upon by the plunger lever (13). This reveals a concave opening in the firing pin block (12) that is of a greater radius than the radius of the firing pin (10), through which the firing pin (10) is allowed to pass and thereby strike the chamber of the firearm.
(8) FIG. 4 is an illustration of the beaver tail lever (14) in isolation. This part is what is acted upon by the beaver tail and in turn engages the plunger lever (13) from FIG. 1.
(9) FIG. 5 is an illustration of the internal firing pin safety mechanism shown in the context of a pistol, for the purposes of clarification. Notice how the trigger bar is not attached to the beaver tail lever, hence it is not responsible for activating the internal firing pin safety mechanism.
