FN509 Trigger System
Volker Precision's FN509 Trigger System is just that...a system. A group of components, engineered, manufactured, and finished in a way that all work together to create the best feeling trigger possible. A smooth and short uptake, crisp and predictable trigger break with virtually no over-travel, and a short and positive reset. Mechanical improvments aside, we aimed to make the trigger shoe both visually apealling and physically comfortable, with a slightly curved face that gives an intuitive finger placement.
