Terrorists

To me, this is the most important factor when looking at the P2000 against the USP-s because the pistol round is the round that Terrorists are most likely to rush on. The USP-S only has 36 bullets in total while the P2000 has 65, almost double the USP-S. This is important because there has been many rounds where a player is holding a location with the USP-S such as ramp on de_nuke, as it is narrow and close quarters 5 glocks automatically over-power the USP-S as the player has to go for the head on 5 individual players while worrying about ammo conservation. With the P2000 ammo conservation is less of a worry and it allows players to cs go community market spam their firing button to make a quick retreat. You can see that players using the P2000 are less cautious with their ammo count and will just try to land the shots on the Terrorists, even just body shots because they have the ammo to do so. This is where I feel the USP-S falls down, as a player without very good aim will easily get slaughtered by 5 glocks while trying to go for the heads where they could've just spammed the 5-man rush with a p2000. While they still would have probably died, their death would not be in vain as they would have probably dealt some damage, even if it's 30 damage to 3 seperate players it can make all the difference in the pistol round. I personally feel like ammo is more important than accuracy when faced with a 5-man rush. The P2000 also gets an extra bullet in the magazine but I feel like this is almost irrelevent as most players have reloaded before their last bullet anyway.

To do this test I fired 20 bullets of each pistol at a wall and then screenshotted it - these were the results: As you can see there is some significant difference, with the P2000 having more vertical recoil than the USP-S which would mean that the USP-S is slightly more accurate, meaning those all important headshots are easier to make.
