I purchased a VP9 a few months ago, and finally had the opportunity to shoot it recently.

No issues at the range and the gun seems to be very accurate, but I have now noticed a problem with the trigger.

If the trigger pressed straight back with even pressure, the gun will fire without issue. If the trigger is pressed with a very slight bias towards my right side, the gun will not fire. No problems if the pressure is directed slightly left.

This is a bit concerning because I would imagine that a perfect trigger press may not always occur under stress.

Has anyone else experienced this? I have never seen any firearm have this problem.

Very strange!

I would send it back to HK. That is unacceptable in a new gun or any gun. I can see it being a safety issue as well with no safety and a trigger that is acting up.

The only issue I have when changing how I press the trigger with not enough finger is pushing the gun to the left, or if too much finger, pulling it to the right....

When the trigger is biased to the right, do you get the proper take up, trigger break and reset? I wonder if the connector has issues. I am speaking from personal opinion as I am not a gunsmih...

The trigger never breaks; you can press it repeatedly and nothing happens.

It goes all the way back but doesn't release the striker? I'd definitely get on the phone to hk.
Nope, never releases.

I got tied up over the holidays, but called HK today and sent them a video of what is happening.

Curious to see what their response is.

I just purchased a new VP40 and am having the exact same issue described by the OP. I sent an email to HK about it but would be interested in if and how your issue is resolved.

I would like to see the video of this also...I shoot left handed when I clean the guns VPs I noticed that the trigger is not as smooth with my left finger as it is with my right finger. I think this maybe something to do with it. Hope you can post your issue you are having.

I haven't posted video to a forum before but if I can figure out how to do it I will. I'm guessing the easiest way is to make one from your laptop camera or phone and put it on youtube and then link to it here somehow, does that sound about right? I'll try that method first I guess.

I should point out that after examining how things move with my vp40 disassembled, the trigger bar is going under the sear unless I push the trigger to the left as I pull it back, in which case it pushes the sear back properly. I can also pull slightly up on the trigger bar as I pull the trigger and the bar pushes the sear back instead of going under it. However, the trigger bar spring looks fine and is attached properly as far as I can tell, so I'm not sure exactly what is going on. Whatever it is, I'm sure HK will fix it, once they have the time to get back to me. I was just commenting mainly on this thread because I'd not seen anything else on the internet that seemed to be the same issue I am having.

To be clear, I have spent a long time researching before buying this handgun and am extremely confident that HK makes some of the best firearms available. I am sure I'm in a very tiny minority with this issue, and when I get it fixed (which I will do one way or another for sure) I will keep this pistol and continue to be very happy to own it. In other words, the purpose of my post is not at all to degrade the reputation of Heckler & Koch, of which I am a great fan. Just trying to interact with those more knowledgable than me.

Yes, a video to youtube or to photobucket would work. I am sure HK will fix it, and like you said, you seem to be in a tiny minority, but that still sucks if you're the one in it! Hoping for a quick resolution for you.

When did you contact HK? If it's been a while I would try again.

I have observed similar behavior, although the sear being pushed back is seemingly random on my particular pistol when disassembled.

How about a view inside? Take the slide off and then rotate the takedown lever back to normal (very important to line the internals up to where they should be for firing), then record the trigger bar/sear area while reproducing both the "fail" and "success" trigger pulls. Might be able to see if something's not lining up right.

Sure.

This behavior seems very consistent.

The first 5 trigger pulls were with a right side bias.

The second 5 trigger pulls were with a neutral or centered pull

The third 5 trigger pulls were with a left side bias.

Thanks for the videos. I'm no gunsmith, I can't tell what the issue is. Definitely needs to go back to Hk. I'd call again if you've not heard from them.

I might have the beginnings of a theory, but I'll need to check it against mine and I gotta go to bed right now. It's going to need to go back to HK regardless, that's definitely not right.
