    I had one fail in the store where I purchased it; brand new pistol.

    Shot one magazine; very nice.

    Second magazine.... something’s amiss.

    Called and the guy on the call wasn’t technical and was kinda in disbelief I think as the pistol had just been released. I clarified what the pistol was doing and he sent me an RMA.

    Pistol came back and all was well in Valhalla. I kick myself for not digging into the pistol and taking photos but, oh well. Nothing is truly perfect.

    Since to date HK to the best of my knowledge hasn't sent out any advisories or recalls, I'm a bit skeptical to jump to the conclusion that there was a failure per se involved. But if you do know something from an authoritative source, please share with us.

    That was according to Bob Schultz of HK as he instructed our class last week when I became an HK certified armeror for the VP series. Cool?

    Great, another thing that can wrong with my 2 year old VP9t... and just when I’m about to to get my HK suppressor for it :-(

    Next time I come down I’ll bring my pistol and you can change out the part for me, Mr. Certified Armorer :-)

    Ok, but I’m not cheap. Although it is safe to say that I pulled down the class average for efficiency.

    I like that, I’ll bring you a sign for your new motto, “I’m slow, but I’m expensive!”

    First thing I notice is the change in the "plug" material, HK would never change it if there wasn't an issue. And I'm not sure why HKCS1 keeps liking JonHK40's attempts to mitigate these failures??
    Is there a reason for a 3rd generation in the plug/adhesive?? Inquiring minds want to know as I have to say it's a bit concerning especially the excuses as this is currently my EDC......

    Good to know your gun is held together by glue when your life depends on it.

    But it’s German glue. Glue, plastic, pieces of wire. Yeah, but at least the slide is machined.

    Even if a percentage of the failures could be attributed to “ham fisted” users, that is still unacceptable from a manufacturing standpoint. My original comment stands, the plug should not fail (separate from the wire), even if someone is going out of their way to decapitate the friggin thing. Bob Schultz did not blame the customer.

    That's significant-what exactly did Bob Schultz say, and what guidance has been provided to HK Customer Service and Techs regarding this? Is it a systemic problem, or a problem that just occurs when a VP is detailed disassembled? Is there a recall or technical advisory on it? As an HK Armorer, what guidance were you provided in dealing with VPs that you service and/or come under your responsibility?

    I've just inquired specifically on this to Mr. Schultz directly in his capacity as Director of HK Training, to ascertain the specific issue(s), it's magnitude, and any corrective action needed. Many thanks for your input, and I'm looking forward with interest (both personal and professional) to the HK response on this. Until I definitively hear from HK on this, I'm immediately suspending using my VP40, particularly for duty, amplified by the issue reported by member Chui on post # 31 on this discussion thread on a brand new VP.

    Best, Jon
