The 1st Gen "Martian Pistol", heavily modified version of the WE X Series IPSC Airsoft Pistol, itself based on the Springfield Armory XD continues to be used by James Holden (Steven Strait), Amos Burton (Wes Chatham) and Alex Kamal (Cas Anvar) after they acquired them in Season 1. It is suggested that by the time of the second season, these pistols are now in the process of being replaced by the MMC.
A 2nd Gen "Martian Pistol", also a modified version of the WE X Series IPSC Airsoft Pistol with a slightly different design, is briefly seen in aboard the MCRN Sirocco.
Note: In the context of the show, the weapons are stated to be "designed to fire both self-propelled rounds and traditional cartridge rounds, the rear of the barrel is vented at the back to eliminate recoil for use in zero-g situations".
The "Star Helix Pistol", which is actually a visually modified Glock 26 Advanced Airsoft pistol (a fictional variant of the Glock 26 with an accessory rail, grip extension and compensated extended barrel originally manufactured by Tokyo Marui) continues to serve as the sidearm of many individuals in the series.
Note: In the context of the show, they are described as a "common gun made from plastic polymers so it can be 3D printed cheaply and reliably. It is designed for reliability and ease of use".
The "Star Helix Long Gun", which is actually an Airsoft Umarex SL9 resembling a Heckler & Koch SL8-4 with a G36K length barrel, handguard, and various futuristic modifications is seen carried by multiple members of the OPA team sent to breach the spin station in "Safe".

This variant is not imported into the US due to its double stack magazine well, which allows it to use flush fitting 10 round magazines.Error creating thumbnail: File missingThe "Star Helix Long Gun" prop seen during a promotional event.
APS UAR
The "Martian Long Gun", which is actually a slightly modified APS UAR Airsoft rifle, is seen in the armory of the Rocinante, as well as multiple members of the OPA team sent to raid the spin station in "Safe".
The 2nd Gen "Martian Long Gun", which appears to be a heavily modified version of the Beretta Cx4 Storm is seen on a gear table aboard the MCRN Sirocco in "Safe". It appears to be an updated version of the rifle used by the Martian Marines in the first season.
Updated mechanical armour worn by members of the MMC, including Gunnery Sergeant Roberta "Bobbie" W. Draper (Frankie Adams), is equipped with machine guns built into the arms, and what appears to be a small missile launcher in the back.
