The Expanse show features numerous weapons: ship-based, small-arms, and improvised. This page is dedicated to hand weapons including small-arms, and improvised weapons. Ship weapons are on a separate page.

Discussion Edit

The TV show appears to use current handguns available in real life, that have been dressed to look futuristic. As portrayed by the TV show, it appears likely that 'smart guns' are the norm in the future although this is never explicitly stated.They are 'smart' in the sense that they will not allow an unauthorized user to fire them. During the fight in the lobby of the Blue Falcon Hotel Miller grabs a revolver out of the waistband of the tac team sent to kill James Holden. Presumably it is an 'old fashioned' revolver without smart gun functionality. After the fight he then picks up one of the newer pistols used by the hit teams, compares it to his revolver, and keeps the revolver. Later Miller, with Holden in tow, ambushes a pair of CPM cops wearing helmets and body armor, and carrying assault rifles. Rather then take the assault rifles along with the armor and helmets, Miller and Holden keep using the pistols they have.

This is suggestive but not definitive evidence that other then Miller's revolver, all the guns are smart guns and the cpm thug/cop weapons cannot be used by Holden and Miller. Holden's bear's one of the MCRN pistols that have been authorized from the Toshi, and Miller using a 'dumb gun'.

This theory was officially shot, possibly to death by Drummer at the end of s2e8 when she takes the presumably Martian pistol from Alex's holster and uses it to shoot an OPA leader and the rebellious {Bridge Crewman} in the head. Upon further reflection it's possible that smart weapons in the future merely need the authorized user to unlock them/take the safety off. So Alex's gun may have still been in the live fire setting when Drummer gets it, because Alex has not turned the safety back on after the initial entry into the tycho command center.
