I was inspecting my pistol, preparing to clean it and checking for function. First thing I did was checked to see if unloaded (that saved my life just now). I pulled slide back and then let it rack forward and left the hammer cocked with the intention of removing the slide. However, I temporarily put it down on the table pointed away from me. The hammer was still cocked at this point. I then stood up, picked up the pistol and somehow it starts dropping out of my hand as I am correcting it swivels 180 degrees with muzzle toward me right at my chest and drops on the table. In the process the hammer dropped so my thumb/finger something got on the trigger during the fumbling. If it was loaded, I would be toast right now. I have never had a weapon go off (meaning even a click) while pointed at me. Well, I am kind of upset that I let this happen. I now have a huge, huge respect for these things. I need to be much much more respectful and careful. Just a friendly reminder that we can never let our guard down and follow all the layered rules (finger off trigger, treat as loaded, know target, muzzle control, etc). Ugh...just feel stooopid. Ok, hope we all learn something! Regards.
