I Am Deadly

I am deadly. I can take a life. Used for protection in the night. Military and police use me. Always taught to never abuse me. Made of cold metal. Extemely careful with every touch now. Make sure only very experience people show you how. Sometimes I'm used in gang violence. Never ever take part in that. I can be very dangerous. One pull of my trigger can end in a splat. If you ever see me you will know what I mean. I look very menacing. The out- come of me isn't at all always clean.....
