"Works well"

Jonathan Wadley on 5/7/2012 9:27:07 AM

Comments and Suggestions: I have a 9mm compact with the LEM that I wanted to lighten. This and the lighter trigger return spring did the trick! Easy install and the pull is half the weight that it was.

Comments and Suggestions: This part along with HKPP2032 was installed in my new P2000. The ease of pull on the trigger has resulted in a much be pattern and consistency in accuracy.

"P 2000 spring kit"

Richard Stone on 2/21/2012 5:36:58 AM

Stars Rating:


Comments and Suggestions: This spring kit #hkpuspc4021, hkpp2032, hkpusp9076, was recommended by HK to improve the weight and reset for my P2000/Lem trigger. The install was not particularly difficult and the results were outstanding, greatly reduced trigger weight w/better reset which makes double-tapp's much easier. improved groupings substantially also. Worth the investment.


"Reducing Trigger Pull Weight"

Mark A Johnson on 2/16/2012 3:56:55 PM

Stars Rating:


Comments and Suggestions: This is a simple way of reducing the weight of the trigger pull. But the best part is there is no cutting, filling or any part that can't be undone. If you have the heavy spring, this will reduce the felt pull weight by about one pound and half off. If you decide to sell your weapon, change the spring and your back to the original trigger. Work wise its the same as cleaning the trigger pocket


"A Must Have"

Comments and Suggestions: This little spring eliminated the stacking element in my trigger's pull..it must be used in conjunction with the "new style" Firing Pin Block and Firing Pin..a must for competition:
