The latest CS:GO Beta update brings new changes to pistols, continuing on on the path of "emphasizing skillful use of the weapons".
The "126.96.36.199-rc1" update, that has been released to the Beta depot, brings new changes to pistols. The Glock, which was unchanged for years, received a buff in base damage and slight buffs in moving accuracy and rapid fire accuracy. On the flip side, the damage at longer distances has been reduced, making the default Terrorist pistol even weaker in long-range battles.
Seemingly balancing it out is the change to the P250, which now rewards longer range engagements against unarmored opponents. The $300 gun now has increased base damage and higher damage at longer instances, but less armor penetration and moving accuracy.
It is important to note that, due to the drop off in armor penetration, the P250 can no longer one-shot helmeted opponents which have full health.
Adding to that, a big change has been made to unarmored aimpunch, which is now significantly reduced, making players without a kevlar vest much more dangerous in duels.
