DOC 1500
My P-07 is my carry pistol. It is amazing how much dirt and thread get attached to my pistol, even in the holster. Maybe you just live a cleaner life than I do. As to the position of the holes we are talking about is within an inch of the hammer, sear, disconnect and ejector assemblies, not where I would want anything to get into the action and gum up my pistol, when I need it most.
You may not use your pistol in this fashion and as a range toy jams are acceptable. Have a Tactical Sport that will jam every 50 rounds or so. In that case I am either getting practice clearing a jam, or I get to throw that run out. Either way no big deal. Defensive pistol not so forgiving on the reliability front. 100% is the only acceptable answer.
Best Wishes and Happy Holidays to all.
