The diametrical opposite of the Commando 553, the .45 ACP "K" is the most basic design ever, made from cheap metal and wood. However: it's completely unbreakable and fires, even straight out of the water. No wonder Agency operatives carried these back in 'Nam...
The Swedish K is one of the more unwieldy weapons in the game, boasting high damage for an SMG but a low rate of fire, unpredictable recoil, large muzzle flash, below-average accuracy and a long reload time. These traits - along with its simplistic iron sights - can make it very difficult to use at range. However, ranged combat is not what this weapon was built for.
With its large collection of modifications, large magazine, and the highest damage per bullet of any fully automatic secondary weapon (tied with the Krinkov, Jackal, Tatonka and the CR 805B), the Swedish K can shred through waves of police officers and SWAT. The damage is high enough that only a few head shots are needed to bring down even the tough Maximum Response Units, rivaling even assault rifles in DPS. However, it has a small ammo reserve, which is prone to running out quickly, though if modded for damage per second and accuracy you can easily multiply your ammo.
When fully modded, the Swedish K can be built for two directions, stealth and room clearing. When the right set of mods are used, the stability and accuracy can be increased to the point to allow for great medium range shooting. For enforcers wielding the saw, the Swedish K can provide better effective range than the Locomotive 12G, but also better damage than using one of the pistols. Going the stealth path will make the recoil even worse than stock, and so the range will become extremely close, but its high base damage can still make it useful with the Silent Killer perk.
This weapon is one of the few that it is highly suggested to use a few times in the Safe house before taking it on a heist. It is also suggested not to use before modifications can be added. Oddly enough, when using a Tactical Laser Module, firing the Swedish K without aiming down the sights may prove more accurate for some players.
It is advised to fire in controlled bursts or to go for head shots due to the low total ammo, giving only two magazines.
Can make for a great secondary to Enforcers using the OVE9000 saw, as the right modifications can give a decent power and decent range weapon OR highest concealment secondary possible. Also, Enforcers can carry ammo bags to counter the low ammunition in reserve.
The Swedish K is one of the worst weapons to wield when electrocuted by a Taser, due to its high recoil and its inability to change its firing rate to semi-auto. The weapon can quickly empty all of its ammunition in its current magazine and the bad stability can hamper aiming to kill the responsible taser. Acing Shockproof or staying close to teammates can remedy said situation.
Although the main flashlight has a toggle switch, the laser sight component of the LED Combo is pressure-activated, meaning the laser will stay on as long as the pressure switch is depressed. This switch is not placed where it should be, however (on foregrips, magazine wells, etc...) and is instead ziptied to the main taclight, leaving no plausible mean for the user to toggle it without awkwardly moving their off hand off the weapon and gripping the attachment itself.
Upon release, the default reticle of this sight was a chevron instead of the retail version's red dot. After the release of the Gage Mod Courier DLC, it was reverted to the regular sight's red dot.
It is functionally the same as the standard Military Red Dot Sight, but the sight's casing is tan instead of black with the line "A-10" scrawled on near the adjustment knob. The sticker on the lens cap's interior also says "I <3 Payday" instead of having a picture of an American flag.
This sight was based on the Aimpoint CompM2 optic. While it is portrayed as a high-zoom scope in-game, the CompM2 is actually a reflex sight, meaning it offers no magnification in reality.
This is one of the few weapons in the PAYDAY franchise to retain its real name, since Swedish K is one of the real-life names of the Kulsprutepistol m/45.
The Swedish K is depicted as a closed-bolt firearm in the game, while it is the other way around in reality.
The Swedish K's default magazine holds 40 rounds despite being modeled after a 36-rounder unit.
The Swedish K is one of the only three non-LMG fully automatic weapon to lack a Custom selective fire function, alongside the STRYK 18c and the Chicago Typewriter (the other two, however, do possess a built-in fire selector switch that the Swedish K lacks, thus permanently affixing it to firing on full-automatic).
According to the info on the Gage Weapon Pack 01 announcement page, the Swedish K's design is "too basic" to accept a fire selector block.
This hints at the in-game Swedish K being based on the military variant of the real-life weapon, as the police model of the real Swedish K, in fact, has a fire selector switch.
The Armored Transport announcement page states that the Swedish K fires .45 ACP rounds, while the real weapon is chambered in 9x19mm, though this could imply a caliber alteration, which would explain the ludicrously high damage.
The stick magazine of the Swedish K is used as an impromptu handhold/foregrip. Such practice is common in real-life, though inadvisable due to improper grip of the hand may displace the magazine (since the magazine catch system of the Swedish K was never very reliable to begin with), cause wear to the magazine catch, or create a misfeed by unintentionally pushing the magazine too hard into the weapon.
