Designed and manufactured for the Springfield Armory EMP and EMP-4. Extreme Service triggers are manufactured to offer the shooter a package of features that will allow years of reliable, comfortable service. Each Extreme Service trigger is made with hardened stainless steel bows that are micro-polished to reduce friction. The solid aluminum shoes are oversize in height allowing fitting to the individual pistol. The "B" trigger is treated with IonBond DLC coating, for an all black trigger. The "N" trigger is natural aluminum and stainless steel for a all silver trigger. The face of the shoe is smooth, free from serrations and holes for the over-travel screw that can chafe and abrade your trigger finger during long training sessions.
DO NOT attempt to turn the over-travel screw! The over-travel screw is permanently locked in place so it can't creep and render your pistol inoperative in an emergency. The initial adjustment to the over-travel stop is made by filing the tip and re-testing until the correct amount of over-travel is achieved.
