Ammunition is plentiful in the early chapters while battling Metrocops in the Canals, but it becomes slightly harder to come by in later chapters, especially in Episode Two, where it is usually only found in some supply crates and abandoned outposts.The USP Match is significantly more accurate than the MP7 and does a little more damage, making it convenient as a backup weapon if the other weapons are running low on ammo.

Instead, one shot should be fired at a time to hit enemies at medium to long range. The USP Match's recoil makes it difficult to quickly fire the gun while retaining any accuracy past short range.In addition, it normally only takes two or three shots to set explosive barrels on fire three or more shots will normally detonate them instantly. On the other hand, it normally takes only two or three headshots to kill.

Aiming for the body is not very effective, especially not if the target is wearing body armor, as it can take up to seven shots at medium range to score a kill. When engaged in a firefight using the USP Match, aiming at the target's head is advised.

The USP Match is not particularly effective against multiple targets, and better when facing off against one or two targets at a time.

In Episode Two, it is found early on while trekking through the Victory Mine. In Episode One, it is found in the City 17 Underground. However, it is possible to obtain the gun earlier than this near the end of the chapter 'A Red Letter Day' by stacking up crates and killing the Metrocop on top of the trains. Gordon first acquires the USP Match at the start of the Half-Life 2 chapter Route Kanal, after defeating the Metrocops beating a Citizen in a maintenance tunnel near the City 17 Trainstation. One of the weapon's most prominent features is its large muzzle compensator that reduces muzzle climb. The USP Match is a reliable and accurate weapon and has a large magazine.
