Firing pin assembly

A firearm comprising:

• a frame;
• a barrel positioned adjacent the frame;
• a receiver that houses a firing chamber and a firing pin assembly which includes a firing pin member having a vertically extending flange wherein the firing pin assembly is spring biased towards a firing position wherein the vertical flange includes a rear surface that includes chamfers that define a channel that extends the entire length of the rear surface of the vertically extending flange to reduce the weight of the firing pin member;
• a trigger assembly having a trigger and a trigger bar member that engages with the vertically extending flange of the firing pin member to inhibit the spring biased firing pin member from moving to the firing position and wherein activation of the trigger assembly disengages the trigger bar member from the flange resulting in the firing pin member moving into the firing position.

A firing pin assembly for a firearm that includes a frame, a barrel positioned adjacent the frame;

• a receiver that houses a firing chamber and the firing pin assembly, the firing pin assembly comprising:
• a firing pin member;
• a spring biasing towards a firing pin member towards a firing position;
• and a vertically extending flange that is sized so that the trigger assembly has a horizontally extending piece that engages with the vertically extending flange to inhibit the spring biased firing pin member from moving to the firing positon and wherein activation of the trigger assembly disengages the horizontally extending piece from the flange resulting in the firing pin member moving into the firing position wherein the flange has an engagement surface of the flange that engages with the horizontally extending piece includes a channel to reduce the frictional engagement between the vertically extending flange and the horizontally extending piece;
• frictional engagement between the flange member and the trigger bar member.
