There are several different kinds of firearm malfunctions: 1.) hangfire, 2.) misfire, 3.) failure to feed, 4.) stovepipe, 5.) squib load, and 6.) double feed. While each malfunction presents its own challenges and procedures to correct the malfunction, most indoor gun ranges craft their firearm malfunction safety rules to prevent a hangfire discharge in common areas such as the retail floor. For this reason, malfunctioning firearms should be kept in the shooting area within the shooting stall with its muzzle pointing downrange.
