Cheap truck gun and bang stick, kind of like a first aid kit and fire extinguisher. You use it when you need to. About 250 rounds in on each one, light strikes about 5 times in total, primarily when it's loosening up or dirty- and only with the garbage challenger buckshot. Caution to ensure that you re- #### the unit when it is broken open, or you will shear the firing pin on closing as I saw happen at the range with another dudes model 101 last summer. my .02
