"Extremely light and durable pistol constructed completely from nano-bound, hard impact plastics and other synthetic materials."
88 Mod 4 Combat Pistol description (from Aliens: Colonial Marines)

The Weyland-Yutani 88 Mod 4 Combat Pistol (also known simply as the Combat Pistol) is a double-action semi-automatic, blowback-operated, magazine-fed pistol chambered for 9mm ammunition.

In 2179, the 88 Mod 4 was used by both the United States Colonial Marine Corps and Weyland-Yutani PMCs during conflicts aboard the USS Sulaco and the Origin Facility on Acheron.


The 88 Mod 4 uses a spring-loaded striker instead of a conventional firing pin. It is double action only so the trigger pull is relatively heavy. In lieu of a blade front sight, the 88 Mod 4 uses a polished ramp with a central notch in the middle to provide the illusion of a dark front post. The 88 Mod 4 uses a manual safety and is the circular button located immediately behind the trigger and is a crossblock safety. The weapon is completely of nano-bound hard impact plastic and other synthetic materials. It included a full 18-round magazine that can be swapped with a 27-round C43 Extended Magazine, however due to the magazine's lenght it make the weapon harder to reload, a S91 Dot Reflex Sight can be fixed with an accessory rail and can be converted into a machine-pistol with the Full-Auto Action Replacement.[1]

  • The 88 Mod 4 in Aliens: Colonial Marines used to have the following attachments: C43 Extended Magazine, S91 Dot Reflex Sight and Full-Auto Action Replacement. This weapon is unlocked at Marine level 10, after the M39 Submachine Gun, making it the penultimate weapon unlocked. It is the only other sidearm in the game and the only sidearm that has to be unlocked before it can be used. Its legendary counterpart, Gorman's Pistol can be used earlier before the base weapon is unlocked, if the weapon is found during Mission 4: No Hope in Hadley's.
