New VP9 trigger bar issue

So I was unfortunate enough to get one of the VP9s with the out of spec trigger bar. It causes the take up to feel like there's an initial gritty break before the actual striker break. Also, upon reset instead of a smooth click it jumps and forces the trigger all the way forward.

I just shipped the pistol off to HK, hopefully they'll get it back to me soon and I can see what all the hub bub about this perfect trigger is. I put 250 rounds through it and did about 1000 dry fires as well with no improvement. I hear this is a common issue.
 
Yeah. Well, I don't think it's a huge issue. The pistol has been reliable save a couple instances of gripping on top of the slide stop. I've learned to place my strong thumb in the Web of my support thumb to keep it away from the slide stop. I've had that problem with many Glock pistols I've owned as well, I think it comes with having large hands.
 
But, I will say it's annoying. Although, all I've had to do was make a 3 minute phone call this morning and wait a few hours for a prepaid FedEx Barcode. Will be at their repair facility by tomorrow. I'm hoping it will come back better than stock and exceed my expectations.
 
It's pretty common. It's not a huge issue, but there were an awful lot of deniers when I first brought the issue up over at HKPRO. There's a long thread that I posted there outlining the problem and what I did to resolve it.

It's a pretty quick fix and really wasn't a huge deal. My little tweak made the trigger so much better. My problem came when the gun got dirty and sandy out in the desert. The trigger would bind up. The pull would become very heavy and gritty and sometimes would fail to reset.

Because of the reliability issues when dirty is why I got rid of it, not because of the little trigger bar issue. I found it was a great shooting gun when kept clean and just shot at the range but the channel where the trigger bar and disconnector slide together is pretty tight and makes it easy for debris to accumulate and grind on the 2 parts as they slide together.

I hate to admit that I was disappointed after a year with the VP9. I feel like it really has great potential but could use a few engineering tweaks to improve reliability. For the time being, I will stick with my hammer fired HK's.

With all of that said, I'm sure HK will take care of you. Good luck with the gun!
 
I'm curious as to what the fix was...


Mine seems fine, a little creep in the trigger, but it's pretty good other than that.
 
If you pull out the disconnector bar, there is a ramp that drives the trigger bar down on rearward travel. At the edge of that ramp it's a sharp cut. Mine had a bit of a micro burr on it, but it was noticeable. It was almost like an initial wall/trigger break before reaching the real one, just not as heavy - unless the trigger was bone dry, then it would be upwards of 12-15lbs.

I removed the disconnect and radiused that transition with a polishing stone. I polished the whole little ramp area where it travels. It totally fixed the issue and many other people on the thread tried it with the same results. It's a simple fix and makes the trigger significantly better in my opinion.
 
Yeah but this is my service pistol, which really sucks, because I just got my job offer and start tomorrow. So I guess I'll be carrying my Taurus 2 inch 38 special until HK sends my gun back. I knew I should have just bought the Block. I owned a Block 17 that I rarely cleaned, and I never had one issue with reliability. I might in fact go down and buy one tomorrow and just sell the VP9 when it comes back. Pretty disappointing.
 
I understand what the issue is and how to fix it, but I'm not an armorer, I have no tools to disassemble a pistol like this, and my life depends on it. So, that's the reasoning I sent it to HK. I thought I'd have more time to get it back before starting my assignment, but now I'm in a pickle.
 
Sorry for your dilemma. I will say that any mechanical device runs the risk of failing. This is coming from a guy that uses Glocks primarily and has seen issues with Glocks, albeit of different natures. When I find a firearm I really like, I try to adopt the "two is one, one is none" mentality. It's easier said than done if money is a limiting factor, but it can certainly help. For your current situation you could always pick up a Glock (and if it's job related you may be eligible for Blue label pricing) and sell one when the other gets back.
 
As far as ergos go, I prefer the VP9 over the Glock many times over.


I thought about polishing up my trigger just for general improvement reasons. Haven't followed the issue obviously, so I didn't know what the problem actually was, but that area is important to trigger feel.


I will admit, the way the trigger works on the VP9 is a little odd. I like to figure out how my firearms work down to component levels, and when I was going through the VP9 it was a little W T F.

They even use the trigger disconnect to force down the sear for the "no trigger pull disassembly"... And this happens during the step of removing the slide.

It was no wonder some people, myself included, experienced stiffness/difficulty with removing the slide at first. Some said they just pulled the trigger, but the mechanism prevents that from actually doing anything... It was just placebo.

It's almost like they made it a little extra complicated because they could.

I love mine, and trust its reliability, but it is a little odd overall.
