So I'm swallowing my pride here and admitting I stupidly injured my thumb while doing a little target practice. I was checking out my moms new handgun, an extremely compact one because she has small hands. I was finding my hands shaky while aiming and had read somewhere that among other things, crossing your thumbs behind the grip will help with steadying your aim. Pulled the trigger (super long pull, hated that) and the gun had an unexpectedly amazing amount of kick which caused to gun to elevate upon firing and the rack slammed back into the base knuckle of my left (offhand) thumb. It's well bruised if not sprained (or even broken to some degree) and of course it was also cut pretty good by the rack. So my question is, has anything like this ever happened to you?
