Guns are weapons that are very common in SMG4's bloopers. Most of the time, they appear from the enemies using the weapon, and sometimes are used by the good guys in case of danger.
Most guns in the bloopers are Glock 17's or Glocks in general. When used, SMG4 uses pictures from the internet or games, such as Garry's Mod. Sometimes, the guns are 3D, when used by Garry's Mod models. Guns are most prominently shown in the Guards and Retards series, such as Swagmaster's AK-47.
