The UMP-45 is the heavy hitter of the submachine gun class. It costs little, is available to both sides and deals more damage per bullet than any other SMG. It also has clear weaknesses. This guide explains its numbers, where it shines and how to avoid the habits that waste it.
To see how it compares with the other six SMGs, read our best SMG in CS2 roundup.
UMP-45 stats at a glance
| Stat | Value |
|---|---|
| Price | $1,200 |
| Side | Both |
| Base damage | 35 |
| Fire rate | 667 RPM |
| Magazine | 25 |
| Armour penetration | 65% |
| Movement speed | 230 |
| Range modifier | 0.75 |
| Kill reward | $600 |
The range modifier is the share of damage kept for every 500 units of distance. A value of 0.75 means damage drops quickly. For comparison, CSDB lists the MP5-SD at 0.87, so the UMP-45 loses damage much faster with distance.
What does the UMP-45 do well?
Its main strength is damage against armour. With 35 base damage and 65% penetration, an armoured body shot at close range does about 23 damage. Most other SMGs do 15 to 19. That means fewer hits to kill a player in Kevlar.
It is also cheap. At $1,200 it costs less than the MP9, PP-Bizon, MP7 and MP5-SD. The $600 kill reward is double what a rifle pays, so two kills already cover the gun. This makes it a strong choice on force buys where every dollar counts.
Against unarmoured players, one close headshot deals 140 damage and kills outright. That makes it deadly on anti-eco rounds.
Where it struggles
- Long range. The steep falloff means distant shots barely hurt. Avoid long sightlines against rifles.
- Helmets. A headshot on a helmeted player does about 91 damage at point-blank range. It will not kill a full-health enemy alone.
- Ammunition. Only 25 rounds per magazine and a slower fire rate mean missed bullets cost more.
How to use the UMP-45 in a round
On T side
Buy it when the team forces and a MAC-10 feels too weak against armour. Push close areas with your teammates, so each fight starts at short range. Trade quickly and keep moving.
On CT side
Hold close angles near the bombsite. Pick spots where attackers must walk into you. A good example is a corner just inside a site entrance. Avoid peeking long lanes.
On anti-eco rounds
Against pistols and no armour, the UMP-45 kills fast and earns $600 per kill. It is cheaper than a rifle and returns more money. Read our anti-eco guide for tips on not giving away free weapons.
How do you spray the UMP-45?
The recoil is fairly mild, but its slower fire rate makes each bullet matter. Tap or burst at medium range. Spray only when the enemy is close. Aim at head height, because a headshot plus one or two body hits usually finishes an armoured player. Practise in a private server with bots, and use good crosshair placement so you need less correction.
Reloading after the 2026 change
Since a March 2026 update, reloading drops your current magazine and any bullets still inside it. With only 25 rounds, the UMP-45 suffers if you reload early. Count your shots, take cover and reload only when you need to.
When not to buy it
If you can afford a full rifle buy, take the rifle. If the enemy will hold long angles, an SMG of any kind is a gamble. If your team needs utility more than a gun, spend on grenades first.
Used in the right rounds, the UMP-45 is one of the best-value weapons in CS2.
Sources and checks
Prices were checked on 1 November 2026 against the Strikeistan CS2 weapon price list. Damage, fire rate, magazine size, armour penetration and movement speed were checked on 1 November 2026 against CSDB SMG stats. The January 2026 MP7, MP5-SD and PP-Bizon changes come from Dust2.us patch coverage, and the reload change from HLTV. Valve can rebalance any weapon in a patch, so the buy menu is the final word.
Frequently asked questions
Is the UMP-45 good in CS2?
Yes, for close-range fights and force buys. It has the highest damage per bullet of any SMG and solid armour penetration, but it falls off quickly at range.
Can the UMP-45 one-shot with a headshot?
Only against a player without a helmet, at close range. Against a helmet, a headshot does around 91 damage before falloff.
How much money does a UMP-45 kill give?
$600 in competitive modes, the standard SMG kill reward. Valve can change rewards in updates, so check current patch notes.
