I've noticed that on a couple G19's I've had come across my bench (I've owned three, one was reduced to a parts gun, I have two now), and had about three other G19s in my hands to work on..................... the trigger bar tends to be a little bit finicky about the way it's bent. Literally, slight tweaking this way and that is needed once in a while on the very occasional gun what has problems. Largely it's all about the relationship between the tail stud on the trigger bar (#62) and the sear release (#83) head. I can't say for sure that the problem here stems from this, but it's another option to look at. There have been a couple guns I've had to file an angled surface on the tail stud of the trigger bar to make it easier to engage the sear release.

For shits and giggles, I worked on a cheap "sold as is" G19, the buyer knew he had me in his corner, so he bought it. He got it, said it would either fire occasionally in full auto mode, but mostly it'd cycle then release all the gas from the mag. My findings? Someone had previously ground the rounded lump off the rear of the trigger bar, most likely in a failed attempt to make a full auto G19. That lump presses the trigger bar down into a position that it can properly engage the sear release so the hammer will lock back after the shot. Because that lump was gone, it prevented the slide from cycling back normally (consistantly), therefore part number 81 wouldn't get pressed down in order to release the firing pin from the mag's valve.

Incidentally, if the gun ever starts to release gas after the first shot, get oil into the area in the hammer's split, and part #74. 90% of the time this problem is fixed by this means. Drop oil in, place thumb in front of hammer and cycle the hammer a good dozen times to work the oil in around the firing pin and the axle it sits on, allowing the hammer to impact your thumb. That should fix it.
