Our patented PRO ACTION flat trigger features the same patent pending design as the PRO ADJUST, but without the adjustability. The PRO ACTION features up to 25% reduction in pull weight while the center rib with curved tip provides fast and consistent indexing. We utilize the same trigger arm geometry as the factory trigger, this prevents trigger reset and binding issues sometimes found in aftermarket P320 triggers.

WARNING!  This trigger is designed specifically for P320s which have been processed through Sig Sauer's voluntary upgrade program or newer. It is highly recommended that the Keres Dynamics PRO ACTION trigger be installed by a licensed gunsmith or Sig Sauer certified armorer.  Installation of this trigger may void the factory warranty on the firearm.


At Keres Dynamics, we recognize a number of customers were concerned with the military drop test results of the P320. While SIG addressed the issue with their upgrade program, we wanted to design our parts to be as light or lighter than the factory upgraded triggers but with the same strength and reliability. In our research, we came upon Tennalum® 7068-T6511 aluminum. Tennalum® gives our parts greater strength than 4130 chromoly steel, but with the lighter weight of aluminum. By comparison, Tennalum® is nearly 250% stronger than 6061 aluminum, but only 1/3 the weight of 4130 steel. This made Tennalum® an ideal choice to achieve our design and performance goals while maintaining the light weight necessary to meet or exceed the drop test standards placed on the P320 for service. Because of this material selection, we are able to manufacture a feature-rich trigger that is 1/2 the weight of the factory trigger, but just as strong.
