Pull out your techNine shoot it off a couple times, then switch to the shotgun fire it once or twice, then switch back to the tecNine and fire it a couple times.Now your tech shotty glitching. Must switch between guns quick or the glitch will not work. And also don't do it in the open go near a wall because people will think your shooting at them and they will team kill you. has happend to me too many times.
