This is a mortar firing pin for a M29A1 Mortar firing system. I have had this firing pin with me since 1986, my entire military career, except the first two years in. I joined in 1984. I have carried it with me in every firefight and every part of the world. I received it back in 1986, it was a spare one. Just in case the main firing pin ever broke. When we turned in the M29A1 for the M252s, I just forgot to turn it in and they never asked for it. We have been inseparable ever since. It even has the same number of jumps I do. I guess I could say it was my good luck charm. I think when I die, I will have it buried with me.
