After reading this thread http://www.hkpro.com/forum/hk-customer-service/145308-p30-v3-springs.html I took out firing pin safeties and springs from my pistols. Now I'm confused. Regarding to HK CS info all models after 2005 should have new style firing pin block and newer ones should have light spring.

On HKparts.net new style firing pin block looks like that:



HK USP Firing Pin Block - HKPARTS.NET

But mine looks like this (left to right: AI HK45C V1, AE P2000SK V0, AI P30L V3):



So we have P2000SK that is pre-2005 (2004) plus P30L an HK45C that are post-2005 (both 2008). All of those seem to have OLD STYLE (EDIT: per info from HK CS below, my blocks are new style, and HKParts.net picture is wrong) firing pin block, and each one have different spring. All have same firing pins (new style).

I'm rarely confused by anything HK, but now I'm. Can someone enlighten me if I have light or heavy firing pin block springs and if I have old or new style blocks. And if I want new style light springs, do I need to change blocks or can keep existing ones?

Um, did it work before? If so then why are you trying to fix it? Seems to me like people want HK perfection then they take apart the guns, voiding warranty I might add, to improve them?
Not trying to be a smart ass, I'm really not. But give it some thought. Does it really matter?

It does matter. There are reason's HK changed. Some we might know the reason's but other reason's i really doubt HK or any Company would say why any change's are made. That link came from HK Customer Service i put it on a thread.

Some with real knowledge will be along shortly. But if me since you have pic.'s i would put a thread in the HK Customer Service Forum also. I'm confused also but sure will follow to see why, best of Luck and Merry Christmas!!

BTW, i really enjoyed your blog and video's!!

The 2005 date for firing pin assembly change only applies to USP series. The P2000 always had the new style assembly since production started(prior to 2005). The improved design was incorporated to the USP series in 2005 and has been in HK45/HK45C since beginning of production. Top picture from HK Parts is OLD style firing pin block for USPs. Left in picture is new style firing pin block with light spring; middle in pic is new f.p. block with light spring and right is new f.p. block with HEAVY spring. Some P30s have the heavy f.p. block spring from factory.

The design to the firing pin was changed to eliminate potential for firing pin breakage. The f.p. block and spring had to be re-designed to accommodate the new firing pin design.

First of all I like to know, or better yet I LOVE TO KNOW! Then I can troll over forums and show how huge knowledge I amassed! :)

Second, if HK changed design, there was reason to do that. I want to make informed decision if I should or not change anything in my CCW guns.

Third, my P30L is competition gun, and while I can not modify it any way (no trigger job, no polishing), I can use OFM parts that are dedicated for this pistol if I will gain, for example smoother trigger operation.

Thank you very much!!!!

I felt this is a case. So I can use new style, lighter firing pin spring in my competition P30L to smooth things a bit. Thank you again.

BTW Anyone have contact to HKParts.net to drop them a word about bad picture?

Yes, you can install lighter firing pin block spring to lower weight of trigger pull (right before hammer breaks)
Wait..."break" is a bad word to use. Hammer will not BREAK...I mean to lower trigger pull weight right before sear releases hammer to strike firing pin. There, I think that is better?

I got what you meant :) My P30L is actually in V0 config (converted from V3) using European spurred hammer and with de-cock button in place. So now I have like 3 stages - LEM take up, firing pin safety take up and sear take up. Lowering weight of this middle stage makes trigger pull smoother and more 2 stage than 3 stage. It works exactly this way in P2000SK (V0 originally). Again thank about taking care of non-USA customer :)

Mine was made in '09 and it has the old cup style FPB. I think they may have changed out part production but still used what they had on hand to ship the guns. Although 4 years of extra parts does seem odd. I never recieved a response to my emails to HK and no one even explained why here when I mentioned it.

Since I changed out my 2010 P30 FPB spring from the original "heavy" spring to the 2011 "light" spring, my trigger is around 1.5 lb lighter measured by a digital trigger weight scale at work, there is a difference.

However, for what it's worth , my Walther PPS FPB spring is still 1/2 the compression weight of the NEW P30 spring. And that gun has a Glock style trigger.

Why did my FPB have the old heavy spring?
Some early P30L had heavy springs. Mine has it as well (it is very early serial just above 300).

I've just checked my BB date code P30 V3 and it also has the heavy FPBS. You can feel the difference when compressing the "heavy" FPBS and the "light" one. I put the light FPBS in mine and the trigger pull is lighter now.

Btw, the new FPB picture on HKParts.net has been updated to the new style.
