M45-series shotguns

The M45 Tactical Shotgun and it’s variants are a series of 8 gauge tactical shotguns designed and produced by Misriah Armory, and adopted by numerous military and law enforcement agencies such as the United Nations Space Command.
The M45-series is favored by the UNSC Army and Air Force over it’s counterpart, the M90-series, thanks to their lighter weight and shorter overall lengths, lending themselves to defensive uses.

=== M45 Tactical Shotgun ===
The M45 TS (and it’s variants) fires 8 gauge shotshells from a non-detachable tubular internal magazine which can lock to prevent a new shell from cycling, allowing the user to load another without first unloading the firearm.
=== M45/E (Extended) Tactical Shotgun ===
The M45/E TS improves upon the original M45 with a lengthened barrel and magazine, a safe action trigger, and an accurized front sight. 
Its barrel was lengthened to 65 centimeters to maximize the performance of 8 gauge buckshot, while the capacity of the magazine tube was increased to 8 shells to reach the same length.
The trigger was changed to a safe action design, combining a trigger, firing pin, and drop safety mechanism, with each being deactivated as the trigger is depressed to sequential positions.
The front sight post was upgraded to a thinner adjustable design, better lending itself to slug rounds in combination with the longer barrel.
=== M45/D (Dual-mode) Tactical Shotgun ===
The M45/D TS improves on the series with an extremely light weight, magnetorheological recoil dampening, and dual-mode semi-automatic fire. Additionally, it retains much of the E’s changes.
Rapid advancements in metallurgical science allowed for a far lighter chassis than any other full-size shotgun, weighing a mere 3.6 kilograms.
The Magnetorheological Recoil Dampening System is actuated by a single-tube damper, which absorbs nearly all of the system’s felt recoil.
Semi-automatic fire is actuated by a gas-operated short stroke piston, and can be quickly switched to pump action to more reliably cycle various lower pressure and less-lethal ammunition types.
