The sound of reloading a pump is awesome and IMHO lulls people into a false sense of security. It can take just over a second to cross a 20ft room. Take into account reaction time you would be lucky to get off 1 shot with a pump. A good modern reliable auto would increase fire power to up to 5. Purists may spout reliability and maybe 50 years ago that may have been an argument. Given the miss fire rate of most modern semi auto shotguns give me auto every time. Comments and opinions please.
