Had a finger in the open action of a buckmark to keep the cleaning rod from hitting the bolt. Patch was good and tight and when it decided to go it jammed my finger onto the ejector (stiff wire) which went in about 1/4”. Hurt like heck. Also when much younger got my left thumb too high with a .25 acp and actually double tapped it before I got my finger off the trigger. First semi auto I owned, glad it was not a .45
