Enhanced Match Flat Sear Spring - Nickel Plated

SKU: HKP-01811

HK Pistol "Nickel Plated" Match Flat Sear Spring - German HK

The nickel plated sear spring is also regarded as a "match" flat spring as it will improve the feel and "smoothness" of the feel when pulling the trigger as it takes up some of the gritty feel. A great improvement and upgrade to any HK pistol. This is a common wear and replacement item on your HK pistol. A great spring to have on hand as they are not common or repairable.

A must have upgraded part to replace the stock "black" flat spring with the Enhanced Match Flat Sear spring. A drop in upgrade for all of the pistols below:

Fits all of the following HK pistols:

  • HK USP 9mm, 40 & 45 models
  • HK USP Tactical, Elite, Expert models
  • HK USP Compact 9mm, .40, .45 & .357 Sig models
  • HK P2000 9mm, .40 & .357 Sig
  • HK P2000SK 9mm, .40 & .357 Sig
  • HK P30, P30S, P30L, P30SK
  • HK45, HK45 Tactical

Nickel plated flat seat spring is the second upgrade I do to all of my USP’s (after extended mag release). Greatly improved the “crispness” of the trigger pull.

I cannot speak too what this part may have changed about the trigger pull, but, my gunsmith gave a thumbs up when he saw it if that means anything. After a few hundred round the gun has ran flawless as one would expect from HK.

"Inexpensive Double Action Trigger Upgrade"

Carlos R on 11/12/2013 11:32:48 AMVerified

Overall Product Rating:

Let's be honest: it might not blow your mind. But I must say I was impressed. I'm a certified HK armorer and bought this to improve the pull on a DA/SA P30. I certainly smoothed out the DA pull.

Good quality. There are two different versions, this spring works for both. You don't have to dissasemble the gun to put the spring in.

HK Parts wan't kidding when they say that this spring will really improve the "feel" of the DA pull. Much smoother and less spongy!
