the photo looks pretty indicative of a press contact wound to me. I don't see any ancillary stippling that suggests the round was fired from any distance. in other words his story is Bullshit and he shot himself in the hand by being a dumb fucghk
That'd be close to my guess too. I've seen worse...a cop pushing the slide from the front to check something....40 S&W at an angle through the length of his hand..I couldn't believe he didnt loose the hand....it didnt look so good, but he still had it.
