I just bought an 11 bullet military. I've read the instruction manual, and I can't figure out what one of the switches on the right hand side does. it has 3 positions, one position is a dot, the middle is a p with three lines and the left looks like an upside down light bulb with 7 lines around it. I thought it had something to do with the lights, but I've tried every position, and checked every light and it seems to do nothing.
