What you want to do is take the slide off, and put a few good drops of oil around part 78 (sits in between the forward hammer split), place your thumb in front of the hammer, and cock/trigger the hammer a dozen times or so.

Nutshell, oil is a must in GBBs

maybe hammer, trigger sear.....something along those parts. I think it was those parts that had problem with venting gas etc.

Is there any wear on the trigger bar? if so check the Solutions threads for posts by JohnnyDo he explains how to fix it i think its a thread I started actually.

striped G19 down checked parts in lower receiver looks good no visiual ware on parts one thing i found in the slide is that the air nozzel seem to stick a little if i pull it forward and let it go it dosent spring back all the way, the small springs in the bottom of the air nozzel are not damaged, (put new ones in) the air nozzel sticks about a quarter inch forward could this problem be coming from a air nozzle problem? thanks guys:banghead:

We'll know if that's exactly the problem if you can fix that.

Since you were able to replace the blowback chamber springs, you should be able to disassemble it again and lube all contact points and rails between the blowback chamber block and the blowback chamber itself. That should allow the chamber to slide freely.
