Enhanced fire-control system
Disclosed herein is an enhanced fire control system for firearms having semi-automatic firing mechanisms. The system comprises a primary trigger, a secondary trigger, and a trigger stop having a stop riser. The trigger stop's stop riser limits breaking a trigger sear interface between the primary trigger and the firearm's hammer. The system is intended to reduce the risk of a firearm being unintentionally discharged as a result of the trigger being contacted with straps or other equipment the user is carrying or wearing, or as a result of contact with something in the environment.
1. An enhanced fire-control system, for use in a firearm having a semi-automatic hammer-fired mechanism, comprising:
a primary trigger 2 ;
a secondary trigger 4 pivotably connected to the primary trigger 2 ; and
a trigger stop 3 located substantially externally to the primary trigger 2 and the secondary trigger 4 and having a stop riser 34 ;
wherein secondary trigger 4 actuates force on trigger stop 3 when secondary trigger 4 is pulled, and
wherein the stop riser 34 limits breaking of a sear interface between the primary trigger 2 and the firearm's hammer unless the secondary trigger 4 is pulled.
2. The enhanced fire-control system of claim 1 , wherein primary trigger 2 has a channel to allow inset and outset of the secondary trigger 4 .
3. The enhanced fire-control system of claim 1 , wherein the sear interface between the primary trigger and the firearm's hammer is maintained when the firearm is in a cocked or a staged position.
4. The enhanced fire-control system of claim 1 , wherein pulling the secondary trigger 4 followed by pulling the primary trigger 2 breaks the sear interface.
5. The enhanced fire-control system of claim 1 , wherein substantially simultaneously pulling the primary trigger 2 and the secondary trigger 4 breaks the sear interface.
6. The enhanced fire-control system of claim 1 , wherein pulling the primary trigger 2 followed by pulling the secondary trigger 4 limits breaking the sear interface.
7. The enhanced fire-control system of claim 6 , whereby limiting breaking the sear interface reduces risk of unintentional discharge of a firearm.
8. The enhanced fire-control system of claim 1 , wherein an upper portion of the secondary trigger 4 has a projection 40 that exerts force on back surface 39 of trigger stop 3 , and trigger stop 3 moves in a substantially lateral direction when secondary trigger 4 is pulled, permitting breaking of a sear interface between the primary trigger 2 and the firearm's hammer.
9. The enhanced fire-control system of claim 1 , wherein the primary trigger 2 has a forward portion 24 and stop riser 34 limits movement of the forward portion, to limit breaking contact of a sear interface between the primary trigger 2 and the firearm's hammer unless the secondary trigger 4 is pulled.
10. The enhanced fire-control system of claim 9 , wherein the stop riser 34 limits downward movement of the forward portion 24 of the primary trigger 2 .
11. An enhanced fire-control system, for a long gun firearm having a semi-automatic hammer-fired mechanism, comprising:
a primary trigger 2 having a lower portion 22 , a rearward portion 23 and a forward portion 24 ;
a secondary trigger 4 pivotably connected to the primary trigger 2 ; and
a trigger stop 3 located substantially externally to the primary trigger 2 and the secondary trigger 4 and having a stop riser 34 ;
wherein an upper portion of the secondary trigger 4 has a projection 40 that actuates force on the trigger stop 3 when the secondary trigger 4 is pulled, and, wherein the stop riser 34 limits breaking a sear interface between the primary trigger 2 and the firearm's hammer unless the secondary trigger 4 is pulled.
