Wolff Extra Power firing pin springs are a must in Colt pistols prior to the inclusion of the firing pin safety mechanism and are highly recommended in all pistols. These springs are approximately 85% stronger than original factory firing pin springs.  These springs are used to provide a greater margin of safety, particularly when trying to meet certain drop test requirements.
