Have a huge piece missing from my left cheek! Blasted guns. I am right handed and use my right eye dominant, and fire as a right handed person. Thankfully my firing stance has not been affected too much. I remember how it happened. Was at the gun store looking at a new gun. Man was it a beauty. The cheek damage occurred right there in the store. I pulled out my wallet, paid for the new pistol, well over $800 for a pistol, and replaced my wallet. That's when it happened, I'm sure. That encounter took a piece of my left cheek. Yup, my left cheek where I keep my wallet was now so flat.
