By only the second reply to my post, someone has already 'Assumed' that my finger was 'Inside' the trigger guard. Tell me exactly WHERE in my story did I say that and where did it say that I'm an untrained handgun user?
It has already been covered by others but I will answer you directly so you will understand where my statements came from.
I did not assume that your finger was in the trigger guard. I knew it was because we all read a story about a negligent discharge. That gun will not go off unless the trigger is pulled. It went off. Trigger was pulled. When the trigger was pulled, your finger was on it. If your finger was on the trigger, then it was inside the trigger guard.
If the gun was slipping and you tightened your grasp, the gun would not have gone off if your index finger was straight out and rigid. This is where we the untrained user comment comes in. If you were a trained user, a number of things would have happened differently.
A) You would have assumed the weapon was loaded
B) You would have known the proper way to clear the weapon
C) When the gun started to slip, you would have put both hands up, stepped away and let the gun fall.
D) You would not have had you finger anywhere near the trigger if you ignored C.
E) You would not have had a ND.
Unless you left out some details from your story, or changed your story, the reasons above spell out quite clearly why what happened was in fact caused by negligence and why in fact you do not handle a handgun like a trained user.
Even if your story changes, you still would have had to not follow one of the lettered guidelines above that a trained user would have. Example - gun fell out of your hands and you grasped for it. You still did not follow D and C, and E still happened.
