The COM-18 is a type of Firearm in SCP: Secret Laboratory. It is a semi-automatic pistol, quick to draw and powerful to use.

Operational Guide

A tactical 9mm pistol. High-capacity and lightweight; these were once the standard issue sidearm for Site-02’s on-site security. Though largely replaced by the FSP-9, some guards still covet the days when their firearm was a few pounds lighter.

___
“Frankly, I think it’s a shame we did away with the COM-18 so quickly. The automatic weapons are nice, sure. To take such a large supply of pistols and relegate them to storage, when there was nothing wrong with them, feels so wasteful. We ought to use them for something.”

-Dr. Gene Hyde, Small Arms Supervisor, Site-02

In Game

The COM-18 is a highly effective sidearm, best used against singular targets. The weapon's light weight and small size allows for it to be quickly drawn in emergencies, while its penetration (55%) makes it a formidable weapon against even Armored opponents.

The COM-18 has 3 possible spawn locations:

LCZ- LCZ Armory (On the right table) [100%]
HCZ- Ammunition Armory (On the table) [100%]
Weapon Locker Type 21 (Possibly inside one of the large cabinets) [14.29%]

The COM-18's reload animation becomes slightly longer when reloading a COM-18 that contains an empty magazine.

Holding down the E key on a player with the firearm equipped will disarm the player.
