HAMMER SPRINGS offer the ability to adjust the double-action and/or let-off function of certain pistols to individual requirements. W. C. Wolff Company advises caution when reducing the strength of the hammer spring when a pistol is used for any critical situations such as law enforcement. Reduction of the hammer spring may compromise reliability of the firearm.
