Our Steel Fire Control Group is made from S7 Tool Steel and polished to enhance the feel of the trigger. We have also reduced the mass of the Hammer in order to ensure reliability in direct blowback firearms.
Included in this set is the Trigger with Springs, Hammer with Spring, Disconnect, Safety with Detent, and the Hammer and Trigger pins. This is everything that you need for installation into your EP9.
This trigger group is not adjustable on its own. The adjustment feature is only available on EP9s SN P20274 or higher.
