Before installing the New York Trigger Spring, be sure that the connector fits tightly in the Trigger Mechanism Housing. If the Connector does not fit tightly - you will need to replace the Trigger Mechanism Housing to ensure a tight fit for the connector.

There are two New York Trigger Springs the Olive (about 8 pounds) and the Orange (about 11 pounds). Either spring should only be installed with the 3.5 pound Connector or the 5 pound Connector. DO NOT USE EITHER OF THE NY TRIGGER SPRINGS WITH THE 8 POUND CONNECTOR
