HK Reduced Power Hammer Spring – 11 lb.

(2 customer reviews)


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.

Fits ALL of the following SA/DA & LEM variants & models below:

  • HK P30, P30S, P30L
  • HK45, HK45 Tactical
  • ALL USP Full-Size Models
  • All USP Compact Models
  • All USP Tactical, Elite, Expert Models
  • HK P2000

Please note: This spring can be used with both soft and hard primers with reliable detonation. Actual trigger pull weights will vary depending on any number of unique pistol variables.

Will not fit the following below:

P2000SK, P30SK, HK45C, HK45C Tactical, Mark 23 or VP series of pistols. See these pistol sections for other hammer spring offerings.

    Just what I needed.

    The 11 lb. hammer spring yields a reasonable DA stroke without any concern for light strikes on common US domestic ammunition. Hard foreign primers have not been evaluated.

    Lighter and smoother DA & SA

    This combined with the GrayGuns short reset kit makes a nice difference in the P30 trigger. While not match grade, considering this pistol is designed for combat and field use and not target/competition. It definitely smooths out and lightens the stroke a bit.
