Firing Pin Block Spring - Enhanced

SKU: HKP-18110

Enhanced Firing Pin Block Spring - Match Grade

An exciting and desirable new offering as a joint collaboration from the widely renowned HK pistol smith Lazy Wolf Guns & HK Parts! This spring was designed by master pistol smith Rick Holm at LWG and is the standard in all of his high-grade custom Heckler & Koch action and trigger jobs for more than 4 years. Lighter than the factory light FPBS, with the same rugged durability and extended life span.

The primary benefit of the Enhanced Match FPBS is to greatly reduce or eliminate the sensation of stacking weight in the trigger pull. This sensation can be felt largely in the factory DA stroke, but also in the SA pull. The match firing pin block spring will also yield a decrease in overall pull weight, varying by what the factory FPBS it replaces. The end user can expect approximately 1 lb. overall weight reduction in pull when using this spring to replace the factory heavy FPBS. It can also be used with other spring configurations throughout the pistol to achieve a specific weight or feel to the trigger pull, such as the popular TLG spring set up. This is simply the finest and best FPBS available on the market and a must-have replacement for all of your factory springs in all of the following pistols. Works in all SA/DA & LEM models.

    A must have upgrade for all:
  • P2000 & P2000 SK Series
  • P30, P30S & P30L, P30SK Series
  • HK USP Full Size (9mm, .40 & .45, except older GEN 1 USP FPBS style)
  • HK USP Compact (9mm, .40 & .45, except older GEN 1 USP FPBS style)
  • HK USP Tactical, Expert, Elite (9, .40 & .45, except Gen1 USP FPBS style)
  • HK45, HK45 Tactical
  • HK45 Compact, HK45C Tactical
  • HK VP9, VP9 Tactical, VP40, VP40 Tactical, VP9SK (replaces the sear spring)

NOTE: Not compatible with the older 'GEN 1' pre-1995 style USP firing pin block assemblies unless you upgrade to the newer style parts.

"Definatey smooths out the trigger pull"

Really smooths out the initial trigger pull. Feels more like a match trigger. You don't even notice the trigger engaging the firing pin block with this spring. Feels like it takes about a pound off of the trigger pull.

"Fantastic Upgrade"

Overall Product Rating:

I had a BD year P30L and the block spring was so stiff that in single action it fought against you just pulling the trigger back to wall. This enhanced block spring made all the difference. The install wasn't hard. Just annoying getting the firing pin back in. I did this upgrade with the 10lb hammer spring they sell and the combo makes the gun feel like a smooth hammer fired gun now. The trigger in da and sa are more than acceptable now.

"Easy install. Worked as advertised"

Overall Product Rating:

Expensive for that little piece but worth it when trying to maximize the trigger feel. Added on a USP9 with a match trigger already installed. DA pull is 9.5 lb and SA is down to a consistent 3 lb with no issue striking primers. Extremely happy.
