I don't see any reason to do any work on the trigger. All I keep reading is that the trigger is the best thing since sliced bread. Some of us know better.................................

It isn't work on the trigger per se. It is work on the disconnect.

Just polished the area on mine today. Resolved the "hump" problem instantly. Smoothly goes back full take up to the break. I would say the trigger is the best thing since sliced bread. Barely any take up, short and crisp 5lb break, short reset, etc. Reminds me why I sold my old M&P40 to buy the VP9.
 
Tomato, tomatoe..............................................I own an M&P .40, and there is nothing wrong with the trigger. If you ever have to use your firearm in a defensive situation, you won't notice what you've done to the trigger, and neither will the bad guy. Apparently, you've not had an opportunity to shoot a lot of handguns. The VP is nothing really. But they have you convinced. Shoot a few thousand rounds through any firearm, and the trigger will be just fine. If you need that much help with your trigger, you must need other things made easy..................................
 
I don't have a VP9 and so none of this affects me but it's curious to see how many people are offended by other people modifying their own weapons. Doesn't anyone here own a 1911?

To each their own. I didn't like the trigger. The M&P40 is accurate, I could put golf ball sized groupings at 21 feet with it. But it was a long take up and a vacant reset. The biggest fix for that was a $150 Apex trigger kit. It also had brass ejection issues, spitting brass everywhere, even back at my face. Had a bloody forehead after one day at the range. Odd stuff.

I used to............just couldn't get comfy with it. Didn't like carrying it either. I have always preferred DA/SA handguns, and the cock and lock thing just wasn't for me. They are nice guns, just not my cup of tea.
 
Uncle Malice -- thanks! A bit of work with 220 grit, then 600 grit, then felt wheel with polishing rouge, and the "hump" is completely gone -- I'm really surprised at the improvement.

At this point, the only thing I can feel before the break is the firing pin block being moved out of the way. I'll look at that some other night.

I know, right?

Odd, man. Really odd.

I have this problem (approx. 1.5 lb hump in middle of take-up). So does my friend's VP9, and one I tried in a gunstore. Mine has slightly improved after about 2k rounds but still noticeable. Otherwise this is my favorite handgun by far. Ordered the armorer's return spring pliars and a spare disconnect to try the OP's suggestion out. If this results in a smooth take-up I will be beside myself with glee :)

For info, you don't need the trigger return spring pliers. While you'll need to remove the parts at the rear of the frame to get the trigger bar free, once the rear end of the bar is free the trigger bar pivots up and comes out the trigger arm without needing to remove the trigger axle.
 
You don't need to remove the trigger bar, you need to remove the disconnect. Unless you also want to try to polish up something on the trigger bar that is. But those are more expensive to replace if you screw it up.

Correct! I just finished dis-/re-assembling my P30 to work on the trigger bar, and had a senior moment. I removed/smoothed the disconnector in my VP9.
 
Rounded and smoothed the disconnector. Slip stones and a dremel buffer wheel lightly with rouge. The whole process took about 20 minutes. Worked great! No "hump" in the take-up.
 
My problem with it is it's not consistent, I can dry fire 20 times and I'll have the "hump" 17 times and 3 times it will break clean after takeup. If I field-strip the gun and reassemble, the first 1-2 dry fires are hump-free every time, and then the hump returns. My VP9 has about 1000 rounds through it, so it's broken in at this point and still has the issue.
 
Read the OP's suggestion. It worked for me. I had a 1.5 pound hump halfway thru take-up.

Got my spare parts and did the disconnector mod tonight, along with installing the HKParts match spring kit. Massive difference, the trigger is very smooth and light now. I wanted to verify the disconnector mod worked, so after installing the modified part I then reinstalled the original disconnector and sure enough the "hump" was back. Put the modified disconnector in and the hump is gone. Big thanks to OP for providing this information, nice to see some GOOD information on the inter webs once in a while!
 
Because it's a damn good trigger . If you just manually cycle the trigger without even cocking the slide , it smooths out nicely . I've got a brand new VP40 with about 3 weeks on it and it's smooth as glass , almost . I'm not a big fan of monkeying around with the disconnector .

I sent in my VP40 to HK Customer Service, I then Dry Fired it 4,300 times holding the trigger back and puoling the slide back enough to re-set the trigger each time.

Here are my images of the Disconnector, it is very clear where the crunch comes from, and it is very clear where Crashmc opines that it is a damn good trigger. I stand with Crashmc in this regard, and as in all things, there is room for improvement.


After about 4,300 dry-fires, the face of the "hump" has been polished as Crashmc states. I would probably have been polished a bit more...however I see little to no reason to fire 4,300 rounds through a duty gun to improve the trigger. If it is a duty gun, the trigger is just fine as it comes from the factory.

Here the Disconnector has been extremely lightly touched up with a dremel tool round very fine grit stone. Just a general smoothing is all.


Here the Disconnector has been polished with a 4 cotton ear swabs and Mothers Mag and Aluminum Polish, swabs were cut in half. Dremel tool was $9-dollars at Harbor Freight.


Finally the end result after 4 more cotton ear swabs and Mother's polish. I just softened the radius of the "hump" a bit.



If this was my only self-defense handgun, I would not modify anything. Having to explain why in court, to the Prosecutor's Expert Armorer witness is not my cup of tea.
 
Been monitoring this thread for a while and finally am frustrated enough to jump in. I had the same stagey-feeling gritty trigger with my VP9, except mine developed over the course of ~3,000 rounds through the gun with regular, thorough cleanings. I polished the hump on the disconnector and noticed a marginal improvement, enough to notice that the gritty feel of the disconnector had been 'hiding' more grittiness from the drop safety.

Dry firing without a magazine in, I can look inside and watch the trigger bar move across the drop safety and visually verify the grittiness is coming from the drop safety. I also pulled the drop safety out and did notice some uneven wear - what I think might be burr marks - on the inside ring of the safety itself and on the drop safety pin. Looks like the culprit. Has anyone else had this experience, especially that weird grittiness developing after a good break-in period?

It's really unnerving to have a pistol age like this, to the extent that I don't know what the trigger is going to feel like next time I pick it up. I'm frustrated and concerned enough that I'm debating selling it and going back to a Glock. At least I know what I'm getting. What do you guys think?
