Variable rate springs function correctly with a wider range of loads than fixed rate springs can. Rate increases as spring is compressed; gives greater protection against frame battering, more consistent lockup and improved feeding, while allowing eas­ier manual cycling of the action. Recoil Calibration Pak contains 1 each of seven different springs; 16½ lb., 15 lb., 14 lb., 13 lb., 11 lb., 10 lb. and 9 lb., plus three extra power firing pin springs. Individual Spring Pak ­contains one variable power recoil spring and one extra power ­firing pin spring. Factory weight is 16 lb.

Chrome silicon steel recoil spring resists taking a set even after thousands of compression cycles for improved performance and reliability. Available in three power ratings, so you can match spring weight to your specific gun and the type of load you shoot. Use Reduced Power 14 lb. spring for target loads with lighter than standard bullets or powder charges, Factory Standard 16 lb. spring for all-around reliability with the widest range of ammo, and Extra Power 18½ lb. spring for smoother cycling and less slide battering with heavy loads. The 14# and 18 1/2# springs comes with an extra power firing pin spring to ensure positive ignition and an extra margin of safety in preventing accidental discharges.
