Most people have encountered a problem with the bolt hold open feature of the GSG-5 not working correctly.

These are pictures looking directly into the breech/ejection port of the weapon.

Thank you for this. I just got my GSG and took it apart for the first time. As I was re-assembling, "clink". I found a spring on the floor and had no idea where it came from. Thanks to this thread I figured it out.

This thread is AWESOME, I *just* read through it today for the first time, after being directed here by a board member on another forum.

I've got a GSG-5PK (1st gen) that I picked up NIB a few years ago. I haven't fired it much, and not at all recently due to a number of feeding and FTF issues I've been having with the gun. First thing I'm doing this weekend is finding and/or replacing the spring in the FIRST photo, mine's gone, and probably dropped out the first time I took the pistol down for cleaning. I've got a spare spring in my toolbox that I found about a year ago, not sure WHERE it came from but I kept it and it may be the original.

I'll also be buying some of the Federal ammo, and blue lok-tite for the three top screws, I know I've never checked them for tightness (I've only had the pistol broken down once for cleaning since I've owned it).

I bought the pistol new before the prices dropped, waaaay before the H&K lawsuit baloney...  so if the prices have gone back UP, this may be about the same in value as when originally purchased?

IIRC, I paid $515 for it about 6 months or a year after they came out, fall of 2008 or spring of 2009.

Thanks again, I'm looking forward to getting this little gem back up and running again!

I finally found the solution to keeping the GSG5 from giving misfeeds.

I shot Aguila through mine because we had 10,000 rounds laying around and I quickly discovered why none of it had been shot. Plainly said, it sucked. Misfires 5 out of 10 rounds and that being low. All light strikes on a brand new GSG 522 including the first 3 rounds. I haven't shot it since and the cold definitely didn't help, but I'm definitely going to be trying CCI.

This gun is new for me, so maybe I need to give it more time.

Here it is over ten years since the first post...I've just discovered I can't get the bolt to go forward - no matter what I do...it will not travel forward if I insert an empty magazine...seems to be permanently stuck in the locked open position...I'm leery of trying to disassemble it while it's in this condition...please advise
