I am glad to hear that you were not hurt worse.
There is a UTube video of a gentleman practicing with a M1911 and you clearly see the unfortunate shoot himself in the leg. I think the pistol was in the holster.
M1911’s were designed to be carried round in the chamber, hammer down in the flap holster. Original WW1 era pistols had wide hammer spurs to assist thumb cocking and the grip safety did not interfere with access to the hammer. Enough accidental discharges occurred lowering the hammer that the SOP became cocked and locked, in the flap holster. Jeff Cooper and the combat types started carrying the things cocked and locked in waist bands, open top holsters, and they even disable the grip safety. Beavertail grip safeties make it just about impossible to safely decock the thing by lowering the hammer.
Ever since I had the safety wipe off on a M1911 I have been leery of the things as carry firearms.
I feel much more confident carrying this M642. This configuration is very fool proof.
And yes, I consider myself in the fool, or future fool category. It is not
if you have an ND, it is a matter of when. I have bumped off the 1.5 pound trigger on my centerfire bolt target rifle. I was at 600 yards prone, I closed the bolt with my right hand and my third finger was sticking out. It got jammed between the back of the trigger and trigger guard. Pulling the finger out caused a ND. That cost me 10 points darn it.
I also have had ND's with my Anschutz small bore rifle. These things have five ounce triggers and you have to really concentrate on what you are doing as you take up the first stage. You also have to teach yourself not to rest the finger on the trigger waiting for wind gusts to die down. Thankfully all of these have been at rifle matches while I was on the firing line and all rounds went downrange. With a pistol, I want to make it as difficult for myself to have the first pistol ND.
If I were to carry an autopistol I want something like this SIG, no external safeties, a decocker. First shot either a long, heavy double action pull, or you thumb cock it.
