MP5K

Lore & Background

In the Payday world, the MP5K is the kind of gun you don't show off at a dinner party. It's the quiet, reliable piece of hardware that sits in the bottom of a duffel bag next to a roll of duct tape and a half-eaten sandwich. The crew—Hox, Wolf, Dalton, and their rotating cast of masked operatives—have always favored practicality over flash, and the MP5K epitomizes that philosophy. It's not the gun you choose when you want to hold a corridor for ten seconds while the breacher charges the door; it's the gun you pull when things go sideways in a service corridor and you need to put rounds on target before the next guard rounds the corner.

In Their Own Story

The elevator dings on the fourteenth floor. Hox steps out first, mask catching the fluorescent buzz, and signals for the others to follow. The lobby is empty—too empty. A single desk chair is overturned, a coffee cup still steaming. Wolf's hand drops to his hip, fingers closing around the polymer grip of the MP5K. The magazine is full. The safety is off. He doesn't need to think about it. That's the point. Three floors up, a vault door is waiting, and a whole crew is counting on the fact that if things go wrong in the stairwell, the gun in his hand is already where his hand is. No fumbling, no reloading, no excuses. Just a short, quiet report and the next step forward.

MP5K — Submachine Gun (SMG)

Category: SMG. Caliber: 9 mm. The MP5K is a low-tier, early-game submachine gun available to all crew members from the very start of a new profile in Payday 2 and carried forward into Payday 3. It is one of the cheapest SMGs on the roster, making it the default close-quarters option before a player has earned enough heist money for higher-tier weapons.

Key stats to note: the MP5K fires at a rapid rate with moderate per-round damage, a magazine in the low-to-mid 30s, and a compact profile that keeps its spread manageable at close range. It is not a mid-range weapon; beyond fifteen or twenty meters it falls off quickly, so it rewards aggressive, close-quarters play.

Attachments and customization: in Payday 2 the MP5K can be fitted with a suppressor for quieter takedowns, a laser sight to tighten aim, an extended magazine for longer engagements, and a compensator to reduce vertical recoil. In Payday 3 the modding system shifts to a parts-and-attachments framework, but the core idea remains the same—suppress it, extend the mag, tighten the spread, and it becomes a very competent close-quarters tool.

Practical role in a heist loadout: the MP5K shines in indoor, tight-space scenarios—bank vaults, office buildings, apartment raids—where you are rarely more than a few meters from a target. Pair it with a suppressor for stealth approaches or a compensator for loud, fast clearances. It is not the gun you bring to an open-air standoff, but in the cramped corridors where most Payday heists actually play out, it is the reliable, no-fuss sidearm that gets the job done while you save your big guns for the real problems.

Did You Know?

• The 'K' in MP5K stands for 'Kurz,' German for 'short,' reflecting its compact barrel and overall length compared to the full-size MP5.
• In Payday 2 the MP5K is one of the few SMGs available essentially from the start of a new career, making it the default close-quarters weapon for brand-new players.
• The real-world MP5K was developed in the 1960s as a shorter variant for vehicle crews and security personnel who needed a compact, controllable 9 mm sidearm.
• Despite being a 'starter' gun in the games, the MP5K's suppressor + extended mag build remains a popular choice for stealth-oriented heist runs well into the mid-game.
