Replace your stock connector with a minus connector for a lighter trigger pull. This connector can be used to achieve a 4.5# down to 3.5# pull weight when using a stock firing pin spring and different combinations of trigger and safety plunger springs (checkout the configurations page for more details). This connector is polished and tuned to provide better performance than a standard minus connector. A connector alone will not provide the same performance as our complete drop-in triggers but is a simple upgrade option. This connector is compatible with all models and generations (except 42 and 43).
