The design of our new Duty Line was driven by feedback from military and law enforcement operators. They wanted our patented Zero Creep Technology and proven stainless steel internals, but with a more tactile feel. To achieve this, we more than doubled the pull weight and length of the first stage. And after the zero creep break we engineered a much more forceful reset. The result? A totally different feel that offers more certainty with every shot. The Duty Line is TriggerTechs interpretation of what Mil-Spec should be.
