Similar to the PMM, the M45 MEUSOC comes with low magazine capacity, but benefits greatly from its high single-shot damage and speedy reload. It can take down Light and Medium Armored Operator at its optimum distance in two bullets.

Learning Area[]

In the No Intel Situation, the player plays as Thermite equipped with a 556xi and a M45 MEUSOC as a sidearm. The M45 MEUSOC is equipped with a Muzzle Brake.

White Masks of the Engineer archetype will use the M45 MEUSOC combined with a ballistic shield when attacking on the protect hostage and bomb mode (during bomb defusal cycle only).



  • The M45 MEU(SOC) was used in the United States Marine Corps until more recently, where it has been phased out by the updated M45A1. It differs from the actual 1911 model used by the real-life FBI SWAT, which is a Springfield Professional 1911A1 Custom.
  • Strangely enough, the gun lacks a rail in front of the trigger guard, which most Special Operations M1911s are equipped with for modularity.
    • This is true for the original M45 MEU(SOC) as it lacks a rail. Its successors, the Kimber ICQB and Colt Rail Gun (M45A1) both feature rails.
