Gun bit and bites...
Garand thumb may be the most famous, but if you mess with guns long enough you can get bit when you least expect it. Last night it was a silly old Pre-M&P .38 revolver. Pinched the crap out of my finger between the trigger and frame. I'm not sure how I even did it. But a good little painful blood blister. It hurts fumbling around to unzip pee or even pick my nose! Cripes, who needs that.
I also remember a particularly painful mash with a Remington 7600 .30-06, while pumping it between the wood and frame. Also a M870 with Mag-pul forend. OUCH! Then there was that Egyptian Hakim 8mm that was a Russian modded design, I figure it would snap a finger clean off like a bear trap! Slides on semi-autos too. The smaller the gun the worse it is. Be careful out there!
