Found a H&K-have Question

Got a P2000 V2 and have put ~400 rounds through it. I'm actually satisfied with the trigger as pulling straight back to the break feels like a DAO(which it is not). However, my wondering mind wants to know if I would have less learning curve if it were a lighter pull-- but not the "lite" LEM--just a lighter break by changing the proper springs. This will be a CCW. HK shooters, what are your recomendations?

The light LEM is accomplished by spring swaps...

The springs you care about are the main spring, the trigger return spring, and the firing pin block spring. If you don't want to go full Light LEM, Google "Todd Green special LEM". That was a very popular setup for LEM.

Are you willing to risk light primer strikes on a carry gun?

Having done that, I get conflicting information on which springs to use. Will changing only the TRS and the firing pin block spring make any difference?

Definitely not.

You don't have to risk light primer strikes. We're talking stock springs made by HK (HK literally has a spec and sells V1 LEM pistols from the factory for certain models). I had idk how thousands of rounds through a P2000 with a 12 lb. hammer spring. Never had a light strike. If it concerns you that much change springs more often.

Buy the springs and try them for yourself. See what combination you like the best. Better to pay for shipping once than multiple times and in my experience someone telling you how it is isn't the same as trying for yourself.

Yes, you can change out To a light trigger return spring and a Firing pin block spring and it will make a noticeable difference.
You can do one or the other or both. Or do the hammer spring along with it or not
In the end you just have to like what you've got. The parts to do this upgrade aren't expensive.

You might want to get the trigger return spring tool. It can make the job a lot easier. You could likely improvise too.

I'll say that the TRS is a pain to change out, there is a tool you can buy from HK parts for $15.00. I just made my own from some cheap harbor freight hemostats.

Here's a spring chart.

This is great info. I am reluctant to do my own gun work. I know of a very good pistol smith in our area. Does he need to be a HK armorer?

If I only want to change the pull at the "wall" and not the take up, which spring(s) would need changed?

This link has HK spring chart which may help. Personally I would first change hammer spring to lighter 12LB, then change FPBS to lighter version, and if you still want lighter then change trigger return spring also to lighter which would make it V1 light LEM.

That's your firing pin block spring.

While I understand the hesitation, some of these are laughably easy. The hammer spring and firing pin block spring involve drifting out a roll pin, and then drifting it back in. The trigger return spring is more work, but there are guides out there and I could give more tips too. If you want to go that route I understand, but really the P2000 is one of the simplest pistols out there IMO. It's an underappreciated design from my standpoint.

Agreed, this is a good plan. The benefit of keeping the TRS heavier is it also makes the reset feel snappier.

Curiously, do many leave the V2 setup as is?

A friend and knowledgeable contributor on the HKPro.com forum installed the V4.1 trigger on my P2000 which originally had the v2 trigger. The pre-travel is reduced by 1/3 and it helps when you don't stage the reset. The pull is around 5 lbs 5.5 oz. according to the installers measurements. I can say that I shoot the pistol much more accurately now. I really love the 4.1 trigger.

That's true, I forget that's even a thing now.

You can do this by yourself for sure. They are harder than glocks but easier than CZ's. IMO.
Watch MosinVirus' videos on you tube a couple times just to get the feel for it.
It's a jigsaw puzzle for men, that's all.

I've watched his videos on the Beretta 92. Very good.

I like it in stock configuration like that on my P2000SK.

This is my dilemma. I like the stock V2, but work harder to shoot it as accuratly at 10 yds as my current cary.

BTW, I've read on the HK forum that a change of the FPBS will lower the "wall" weight. Can anyone verify this as it sounds like a simple solution?
