The official UMP-45 Description states:
“The misunderstood middle child of the SMG family, the UMP45’s small magazine is the only drawback to an otherwise versatile close-quarters automatic.”
The UMP-45, or KM UMP45, as it was previously known, is a submachine gun featured in the Counter-Strike series.
The UMP-45 is a powerful submachinegun available to both teams. Many players tend to use it because of its high damage and penetration (the highest of all SMGs in Global Offensive). It has the lowest rate of fire out of every SMG (although the fire rate has been greatly increased in Global Offensive). For those reasons, the UMP-45 is very uncommon among players in the older games, but relatively common among players in Global Offensive, along with the P90. Currently in Global Offensive it costs $1200 instead of $1700.

Prior to Global Offensive, if equipped at the same time with the K&M .45 Tactical, the two will share an ammo pool of 100 rounds as they share the same cartridge.
The UMP-45 is a fairly light weapon. While wielded, the player’s movement speed is 250 units per second, meaning they suffer no speed reduction. In Global Offensive, this was lowered to 230. The UMP-45 is one of the many weapons that have the ability to shoot underwater.
