Wolff Hammer Spring for Ruger #1, #3 Extra Power

The Wolff Extra Power Hammer spring improves lock time and ignition problems common with these rifles. Notes:Extra power striker springs decreases the "lock" of the rifle. The lock time is the amount of time from the moment the striker is released from the sear until the striker hits/ignites the primer. The shorter the lock time, the shorter the time the rifle has that it can move off of the target.
