Closing thoughts

As the free starting pistol for the Terrorist team, it is the worst pistol in the game and performs considerably poorer than the Counter-Terrorist equivalents; because of this it could be argued that upgrading your pistol is more appealing on the Terrorist team, but most players will still opt to instead spend their money on utility grenades or armour.

The pistol does support an alternate burst mode, which will fire 3 bullets in quick succession, but this is often hard to control and most players see more consistent results without this.

The USP-S is one of the free starting pistol options for the Counter-Terrorist team. More frequently used than the P2000, it comes with a silencer in exchange for an extra bullet. In any case, it performs better than the Terrorist default.

Right clicking allows the player to remove the silencer, but this just makes the weapon slightly less accurate (and louder of course).
