It looks a little like that retainer clip that goes in/out the upper right side of the frame during disassembly.

 

Do you mean the safety clamp part number 20 here https://www.gunpartscorp.com/gun-manufacturer/heckler-koch/auto-pistols-hk/vp9 ?

 

I just did triggers on my VP9 & VP9SK. I don't recognize that part.

While it may resemble #20, neither hole is open. They both appear to be closed.

Do you notice anything when dry firing ? Does everything appear to be tight ?

After blowing your pics up and looking close, I'd say no it's not.

I didn't take anything apart on the rear portion of the housing. Even so, the schematic shows nothing that looks like that in that area.

One hole is open the other is closed. When dry firing everything appears to be fine.

 

If one side is open that part holds the right side slide release in place.

Pull the slide off. On the right side silver rail there is a small rectangular cut out.

Make sure your right slide release lever is pushed all the way in. The open portion of your mystery parts goes in that slot. Puch down on it to lock the lever in place.

 

By open I mean that one hole is drilled all the way through the other is not. The part is made of metal. You are talking about the safety clamp right? This is not the same part. Here are a couple of pictures next to the TRS pliers for size reference. Thanks.

 

I swear though that your pic doesn't look like the part that I am describing. See scan attached.

No that’s definitely not it. I’ve got the part you posted installed.

 

I won't even speculate on how that piece ended up on your lap. I'd say that isn't a part from a VP9.

I've done 2 triggers in the last 4 days and my memory is still fresh.

Did you take anything off of the rear portion, behind the grip ?

 

I took out the sear housing and changed the seat spring and swapped the trigger. No other disassembly beyond that. As small as the part is it could have been sitting on the table when I started. I doubt I would have seen it. No idea where it could have come from.

 

Well, hold onto it for now but I'd bet it's not part of the gun.

Good luck !

 

Thanks. I put it in the bag with the old trigger, so I can find it again if I ever figure out what it goes to.

 

What trigger did you get. Looks like my Lazy Wolf C1?

I really enjoyed doing it myself. A real sense of accomplishment.

 

I got th F3, what a difference. I polished the trigger bar and disconnector while I had it apart. Smooth pull, no grittiness and no over travel. Breaks right at 4.5#.

 

It's a Gov't tracking device. You are under federal investigation.

 

Just had my VP9 open for a trigger and firing pin upgrade. I don't recognize that part

 

This part is the tigger safety block and is NOT supposed to be removed from the frame. It is a bonded in part.

Another thread was started about this and HK Customer support mentioned a frame replacement is more than likely necessary.
