The Cajun Gun Works 13lb Hammer/Main Spring is one of their most popular music wire 13# hammer springs. It is coloured coded blue, so you don’t get it confused with other strength springs. This spring must be used with a Reduced Power Firing Pin Spring.

Note: This is a light spring, and typically used in competition. Not using the correct corresponding parts, may result in failure to ignite. If in doubt, please consult with your gunsmith.
