An exciting new offering as a joint collaboration from the widely renowned pistol smith Lazy Wolf Guns & HK Parts! This custom spring was designed exclusively by master trigger smith Rick Holm at LWG where his custom spring line is used in all of his high grade custom Heckler & Koch action jobs for more than 4 years. Appropriate for use in competition or defensive pistols for maximum trigger pull weight reduction. This spring bridges the gap between the 10lb and the 12lb pound hammer springs, offering the end user more ability to fine tune the break weight of a pistol. Used with light springs through the rest of the pistol will drop the single action break weight to approximately 3.75-4lbs (SA/DA & LEM), and 8.5-9lbs on the double action. Works in both LEM models and standard Non-LEM models alike.
