I replaced the serrated trigger with a smooth trigger in a G19. After 400 rounds and probably thousands of "dry fires" on the new trigger bar, I noticed that if pressing the trigger hard (very firm grip, etc.), to the stop, after a dry fire, a secondary "click" is heard. This is the trigger bar "cruciform?" releasing upward. Is this normal/a problem (I am concerned about going auto, etc.)? When racking the slide, the trigger resets per normal. I cannot detect any problem with resets when releasing the trigger after racking the slide. Thanks for any advice.
