S&W 12 lbs. Rebound Spring

12 Lbs. Trigger rebound spring. Helps Reduce your Double Action Trigger pull when you are working on your double action Smith & Wesson J, K, L and N frame revolvers. If you are using our Series I Stoning Fixture or using our New S&W CNC machined trigger these springs are a must. The Factory Trigger return spring is 18 to 19 lbs. These springs are a must to lighten the trigger and let-off functions for smoother and easier trigger pull.
