There was a month where I didn't want to shoot it because that second round would go off and miss the berm often enough. So I took out the bolt carrier and held the hammer down with my thumb to gage the distance in trigger pull between the two sears which hold the bottom of the hammer disengaging and the other sear engaging the top of the hammer, should the shooter hold the trigger down. Obviously there was a huge distance in trigger pull where none of the sears would engage. I decided to get those two sears back into position to catch the hammer; hence the quick jerk and quick release. That solved the misfire issue.
Correct, jerking the trigger might not be as accurate but I only need to hit a milk jug at 70 yards on the front lawn without neighboors hearing a bullet go tearing across the countryside.
