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 pistols for maximum trigger pull weight reduction.

This spring will yield a significant overall weight reduction. When used in conjunction with the light firing pin block spring and the light trigger return spring through the rest of the pistol will drop the single action break weight to approximately 3.5-4 lbs (SA & LEM), and 8-8.5 lbs 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: depending on fitment & tolerances of each pistol, this spring may cause intermittent light strikes when using some HARD PRIMERED AMMUNITION. Test & evaluate with your preferred ammo. If you experience this issue: use only soft primered factory ammo, purchase soft primers for reloading ammo, or jump up to the optional Intermediate 11 lb. spring weight.

Actual trigger pull weights will vary depending on any number of unique pistol variables. WILL NOT fit the P2000SK, P30SK, HK45C, HK45C Tactical, Mark 23, or VP series of pistols. See these sections for other hammer spring offerings.

    I have this in an HK45. Makes a very noticeable improvement of both the DA and SA pull weights. I reload and shoot a lot of factory ammo from 185-230gr and have never had a malfunction of any sort.

    This definitely made the trigger pull lighter in both DA and SA but is also reliable. I ran 200 rounds through my HK 45 with no light primer strikes. Very fast shipping as well!

    Big difference in double action pull. I liked it so much I bought another one for my wife's P30. I highly recommend it.

    I heard in a forum that a lighter hammer spring might help with the 14 trigger pull. Yes, it help in both single and double action modes.

    I ordered hammer spring, trigger return spring and firing block spring all together. Installed all myself. Definitely improved double access.

    This truly is one of the best if not the best upgrade for the P2000. It really brings the weapon into the modern era of DA/SA firearms which seem to be trending on a sub 10 lb. DA pull. I did not notice much of a difference on the SA pull; never had an issue with it on the stock spring so wasn?t really a selling point for me anyway. All in all you cannot go wrong with this spring.

    This trigger spring along with the Light Firing Pin Block Spring is an EXCELLENT Must-Have trigger modification on P30 Series pistols. The difference in performance achieved is phenomenal. There is one more part of the modification - the Light Trigger Return Spring change - however; it is not necessary to change the trigger return spring to achieve great trigger performance. It would be a beneficial change though if the pistol is used for competition/match shooting as it shortens the trigger reset point somewhat.
