Hi


I think I have a faulty trigger on my VP9, when I pull it I feel like using a file on some metal, the trigger bar is straching something hardly during its movement

the problem disappear if I press down the bar

wondering if is normal the up and down movement of the bar when I pull the trigger...

I shot about a 1000 rounds and the problem didn't change in any way

this is the video of the problem: https://youtu.be/TsZGwiTUD8A

I have the opposite where the trigger is scratchy/gritty on the reset when the bar is pushed down, but smooth otherwise. I'm reasonably happy with my VP9 but it does seem like there's some cost cutting measures and a general lower quality and QC issues than some of their older "no compromise" guns.

I've had no issues with any of my 4 VP9s, triggers are all consistent and get smoother more they're shot.

Trigger bar doesn't work to well without the slide sitting on top of it .
same problem with the slide on, I removed to show the bar movement

Clean it?
cleaned and lub a lot of times since I bought it, no changes



I brought it to my dealer, they'll probably change the bar and let me know...

My VP40 trigger is excellent, out-of-the-box. The break seems "softer" than the break on my Glocks, although actual pull/break weights are probably about the same (depending, obviously, on the comparative connector/spring set-up chosen for a given Glock) I did put a drop of Weapon Shield on it where it interfaces/rubs against the receiver. Although different in feel, the pull/break on the VP40 seems as nice as the on on my P30L V1 LEM.

Glock reset point is quicker than on either the VP or P30.

Best, Jon

The up and down motion is normal. The scratching is also to some degree normal. Some seem to have it, some don't. People's individual sensitivity to such things likely plays a part in the varying reports. Two places it can come from, where the little trigger bar catch looking thing rubs against a hump in the disconnector and the firing pin block safety. The disconnector hump can be smoothed out and largely improved. See this thread: http://www.hkpro.com/forum/hk-handgun-talk/219658-improved-my-vp9-trigger-pull-dramatically.html
The firing pin block resistance is going to be there no matter what. (Unless you remove the safety I guess. Please don't do that.) The grittiness might be improvable by polishing the surfaces that rub together, but I decided it wasn't worth taking the safety lever out to do it. It will naturally smooth out a little over time. Mine has gotten gradually better. It's at 2000 rounds right now, and I spent some time trying to wear it in probably to the tune of 5-10k more dry cycles on top of that. It sounds like an ordeal to send it back in to HK for you, so I would 1) decide if it's really a problem for you and 2) try these fixes first before sending it in. I sent mine, and they sent it back saying that amount of "snag" was normal.
