When I was young I had mammoth smoke bomb explode in my hand (yeah, I didn't read the label). It didn't break the skin. You seem to be OK But, DANG man that must have scared you half to death? Were you shooting reloads or something? Hope your ok.
Aquilla and Amerk or aluminium will never see one of my guns. I never did trust them and never will. Others may disagree and that's OK with me, but I'll never use them.
did your finger catch the slide or was it an ammunition problem
