If we are going to allow teachers to " carry" we need to do away with all of the printing and concealment nonsense and let them carry an effective firearm than can getbthebjob done with an armed probabaly heavily armed subject shooting everything that moves .In that circumstance if I have to settle on a handgun I want my 629 loaded with 240 grain jacketed hollow points at 1000 fps I would much prefer a rifle maybe my m1a but I guess that would be pushing the limits a little too much . But why couldn't a classroom have a carbine locked in it with the teachers having access and training .
