VP9 dead trigger due to impact issue (split from Personal SIG 320 Journey thread)

[Doc_Glock]

Can you describe exactly how you are getting this? I have a VP9SK and three or four VP9 full size I can test.

Nylon hammer works better than rubber. It appears the sharpness of the hit is more important than the magnitude.

Doesn’t this depend upon whether the issue is defective parts/tolerance stacking vs a design issue. With the PPQ I am confident it is a design issue.

Just tried this with a new PPQ (FCN6xxx SN) with about 300 rounds through it. Wacked it on the butt a few dozen times with a soft-faced mallet (nylon with thin rubber coating) at different angles and varying the intensity of the strikes. In fact I once hit it so hard I knocked it out of my hand and it landed on the floor.

Just like my previous drop testing of this pistol, I have yet to get the striker to release with an impact.

First of all, allow me to point out that I seldom miss an opportunity to make myself look stupid.

I said that my pistols were coded DE and BE, well.... both pistols have both a BE and a DE on them. Obviously, neither of my pistols were made in 1934 or 2034, so BE must be the accurate code for both pistols.

I called HK and talked to two different guys in the repair department. They said they had spoken with someone that conducted this test in the past. After it being brought to their attention they extensively tested some VP9's to see if they could induce the malfuction by drop testing it with a loaded magazine. They were not able to get the striker to drop. They also mentioned that the VP9 has been through several drop tests conducted by LE agencies and they are unaware of a single failure of any kind.

In short, if the only way to duplicate it is by hitting it with a mallet with no magazine in it, they are not concerned with trying to fix an issue that does not appear to have real-world application in their opinion.

I applaud the guys at HK for treating me with respect, even though it must have been an irritating phone call to field.

Forgot to add I did the same on the rear of the slide. As far as I'm concerned, my PPQ has passed the Internet's Beat Your Pistol with a Mallet Test with flying colors.

Kudos to the HK guys.

Bet you $5 PF dollars, if you sent me your slide, I could make it drop the striker, on video, with some vigorous reloads.

Ease up on the porn watching.

Well, since you live far, far away with the polar bears, what if I send you the OEM plastic sights from my slide and see if your gun still malfunctions with them?

VP9s drop their striker when tapped on the bottom of the grip. That completely rules them out for me. Otherwise great guns.

I just wanted to post this video here to demonstrate how I think a VP9 could end up with a dead trigger. Cop goes down directly on to his back. May or may not have hit the bottom of the grip of his pistol, but this is exactly the scenario where I think the VP9 is less than ideal. You could end up with a dead trigger and not even know it.

Is this true - "the only way to duplicate it is... with no magazine in it" ? Have people who successfully created this problem posted results of attempts done with a loaded mag?

If the problem happens only when the VP9 is cleared, then this poses no danger to the user and is not a problem at all. Loading / chambering would reset the trigger and make the loaded weapon subsequently immune to the issue.

HK's Tech Support/Repair department is small, but extremely professional. I've consistantly had excellent discussions and advise/assistance from them.

I've qualified with, and feel comfortable carrying my VP40 for duty. In the relatively recent past (last year) HK has corrected an out-of-spec triggerbar (which necessitated my pulling the trigger to field strip) and gave me a courtesy opgrade regarding the bearing on the trigger return spring (probably unnecessary, but I prefer the ugraded part just on general principal if nothing else).

Best, Jon
