Half-cock trigger safety assembly

1. A trigger assembly for striking a firing pin of a firearm, the trigger assembly comprising:

a hammer having a stable cocked position, a stable safety position, and a stable uncocked position;

the hammer having a hammer sear surface and a hammer safety engagement surface different from the hammer sear surface;

a trigger having a forward portion with a first area and a second area different from the first area;

wherein in the stable cocked position a first area of the forward portion of the trigger contacts the hammer sear surface;

wherein in the stable safety position the second area of the forward portion of the trigger contacts the hammer safety engagement surface and the first area is not in contact with the hammer.

2. The trigger assembly of claim 1 , wherein the second area of the forward portion of the trigger is adjacent to the first area.

3. The trigger assembly of claim 1 , wherein the second area is parallel to the first area.

4. The trigger assembly of claim 3 , wherein the second area is located closer to a rearward portion of the trigger than the first area.

5. The trigger assembly of claim 1 , wherein in the stable safety position the second area is parallel to the hammer safety engagement surface.

6. The trigger assembly of claim 1 , wherein the hammer defines a recess adjacent to the hammer safety engagement surface; and

wherein in the stable safety position the hammer sear surface faces said recess.

7. The trigger assembly of claim 6 , wherein the hammer sear surface is received within the recess defined by the hammer when in the stable safety position.

8. The trigger assembly of claim 1 , wherein the second area is positioned radially outward from the first area relative to a rotation axis of the hammer.

9. The trigger assembly of claim 1 , wherein the assembly is a drop-in trigger module comprising a housing that retains the trigger and hammer in relation to one another.

10. The trigger assembly of claim 1 , wherein the hammer includes a disconnector engaging surface opposing a firing pin striking surface of the hammer.

11. The trigger assembly of claim 10 , wherein the trigger defines a pin opening for pivotally connecting a disconnector thereto.

12. The trigger assembly of claim 1 , wherein the hammer is rotatable a first angular distance from the stable cocked position to the stable safety position;

wherein the hammer is rotatable a second angular distance from the stable cocked position to the stable uncocked position; and

wherein the first angular distance is at least half of the second angular distance.

13. The trigger assembly of claim 12 , wherein the first angular distance is at least 60% of the second angular distance.

14. The trigger assembly of claim 12 , wherein the first angular distance is at least 70% of the second angular distance.

15. The trigger assembly of claim 12 , wherein the first angular distance is at least 30°.

16. The trigger assembly of claim 12 , wherein the first angular distance is at least 40°.

17. The trigger assembly of claim 1 , wherein the trigger assembly is a single stage trigger assembly.

18. The trigger assembly of claim 1 , wherein in the stable safety position a trigger release barrier surface of the trigger is arranged to engage a hammer release barrier surface of the hammer to prevent movement of the trigger from releasing the hammer and allowing the hammer to rotate into contact with the firing pin.

19. The trigger assembly of claim 18 , wherein the hammer release barrier surface is transverse to a hammer safety engagement surface that engages a trigger safety engagement surface when in the stable safety position.

20. A firearm comprising the trigger assembly of claim 1 .
