| So I pull the trigger, it fires, then I release the trigger for next shot, fires again. I've looked it over, does someone have an idea what I have backwards, broken, ect....? Note, it does not do it every time, maybe 90%. I notice when I take my upper off, it does it a couple times when I manually cycle it, then goes back to normal. So dry fire, I pull the trigger, fire. keeping the trigger down, i "re-cock it" and release the trigger it fires again. |

It could be an easy fix. The disconnector spring that sits in the trigger may be bound or twisted. The hammer, trigger, or disconnector may not be mating with each other well. There are several possibilities.
The most certain way to almost guarantee that you fix the problem without trial and error is to just swap the hammer, trigger, disconnector, and spring with a new set. Otherwise, start looking at and checking the function of those four parts. ETA: beaten to the punch. |

So you dry fire, hammer goes down. You press the trigger again to dry fire, and the hammer drops again?  Duh, read it againImpossible for that to happen. I doubt that's what he means. EDIT: Yup. Do what the posters above said, and replace your disconnector, and or trigger/hammer. |

1. Take the upper off the lower.
2. Depress the hammer with your thumb. 3. Move the safety lever to fire. 4. Pull the trigger and keep it held in while you ride the hammer up on your thumb to prevent it from cracking the lower. 5. With the trigger still being held in push the hammer back down. 6. Verify the hammer stays down after a click. If it doesn't your disconnector isn't catching. If it stays down keep going to #7. 7. Keep thumb loosly over hammer and release trigger. 8. Hammer should move slightly up and click while still staying down. If it releases the hammer isn't catching on the trigger surface. 9. If it stays down through all of these steps just swap the parts. Keep your thumb loosely over the hammer to keep it from flying up and cracking the lower. |

Actually that is what you are checking for when doing a Safety Function check. Step 4. Hold Trigger to the rear, pull Charging Handle to the rear and release Charging Handle. Then release pressure on the Trigger with a slow, smooth motion, without hesitations or stops, until the Trigger is fully forward. AN AUDIBLE CLICK SHOULD BE HEARD - THE HAMMER SHOULD NOT FALL.
Step 5. Repeat the FIRE position test FIVE TIMES. ... |

Even with a botched disconnecter. We're not talking double action pistols, but I needed clarification regardless, to know exactly what he was talking about. |

Both surfaces look 100% Buy another hammer and trigger and mark the ones in your gun right now with a marker. Then start with the new unmarked parts installed and function check. If needed, swap those two back and forth with the marked set until you identify a pair that works. You could have to use one marked part and one unmarked part if the new set also doesn't work by themselves. If no combination of the parts work, then it might be the location of the hammer and trigger holes in your lower. Edit: And also when you have the parts out make sure the disconnector spring has whichever end is larger inserted into the base of the trigger and that it seats squarely down into the trigger. I usually insert mine and then push down on it a few times with a small punch to make sure it seats correctly. |

Perhaps but if you read exactly what he did to test it while dry firing you'll see he does exactly what the Safety Function Test does. so it is ready to fire, I pull trigger and it fires, keeping the trigger depressed, I charge it again with my other hand to simulate it actually fired, and then when I release the trigger it fires(not pulling the trigger, but releasing the initial pull).
Seems he's solved it anyway.
