I know many folks who have had minor Garand thumb but somehow the only time I got hurt, aside from High Powers biting me so much I had scars visible for 20 years, was a Beretta 92.
Was demoing a feel-with-pinky-finger style of chamber check, hadn't done on the M9 before. Not a lot of slide, I slipped, got my pinky stuck AND I couldn't open it myself, AND the extractor tried to extract my finger. Once a friend opened the slide, I had to pull and twist to actually get my finger out.
There was flesh under the extractor claw, that had to be removed with a dental pick! That left a mark, though now around 30 years later you finally can't see that scar either.
