Your position is not very widely supported by the instructor community. Think back to your training... what are you required to do when you pull the trigger and the round doesn't fire? Well you don't pull the trigger again. You maintain a downrange direction for 30 seconds and then remove the misfired round, depositing it in a safe-box. What else went wrong? Don't put the gun in your "off" hand. maintain the proper grip on the weapon during unloading. Yes, I may be an instructor, but you're actions in firing a second time go against everything taught in basic safety 101. Most certainly goes against the curriculum for NRA First Steps Pistol and NRA Basic Pistol. The gun didn't "go off." It fired as a result of your handling. There are proper procedures for handling defective rounds. And the first one is not pulling the trigger on a defective round a second time. I think your 40 year safety streak is over. Had you done this in class you have been dismissed immediately. No disrespect intended. It can happen to anyone.
Did you miss the part of my post where I stated that I waited 30 seconds? The reason I attempted to fire it a 2nd time was because the slide was in full battery and stuck. After multiple attempts to eject the round, holding the gun in a downrange position, I was forced to switch hands. I couldn't move the slide even with the push/pull method , it wouldn't budge.
You can't put a dud round in a box or bucket if you can't get it to eject from the firearm. This particular circumstance left me no choice but to handle it in the manor that I did. I realize you weren't being disrespectful in your reply to me, and I appreciate that. On the other hand, I will still not refer to this as a "negligent" discharge.
Thank you for your response.
As always, stay safe.
