HK P7 PSP problem :(

[Suputin]

Had my P7 PSP out today and ran into a problem I have never seen before.

After firing a shot, the trigger does not reset. It stays back. If I decock and recock, the gun will work for another round and then the trigger doesn't reset again.

Anyone run into this or have an idea of the problem?

If you hold the trigger and fire with the grip cocker (?) does it do anything funny?

It won't do that. The cocker stops before it can drop the striker.

OK, I figured it out. The cross pin that holds the barrel in place also acts as a stop for the trigger rotation. The pin had moved a bit to the left which allowed the top portion of the trigger to ride over it and get stuck in that position.

I tapped the pin back into place and it all works again.
