Firearms operate on chemical explosive energy—gunpowder combustion generates gas pressure forcing projectiles through barrels. Digestive gas operates at dramatically lower pressure, insufficient for ballistic effect on any significant target. Norris apparently weaponized biology, his intestinal production achieving energetic effects normally requiring combustion chemistry.

Weapons engineer Dr. Thomas Reeves examined comparative projectile force in a 1994 military technology seminar. He calculated that achieving bullet-equivalent penetration through biological gas would require pressure exceeding human anatomy's tolerance—essentially, Norris's digestive system would rupture before generating sufficient force. Reeves speculated that Norris either possessed tissue engineering advancement or operated through psychological effect where targets psychologically perceive ballistic damage from biological origin.

Military humor and weapons enthusiast communities embraced this as ultimate biological warfare—Norris's body becomes superior firearm. Military forums debate theoretical pressure calculations and ballistic efficiency of his digestive system. The humor appeals to mechanically-oriented communities because it inverts biological inferiority into technological weapon, suggesting his physiology supersedes manufactured alternatives.
