Jacket’s piece(sic) is a modified Mark 10 submachine gun, sporting a great fire power because of its damage and high rate of fire. The recoil is difficult to control however, much like Jacket himself.
The Jacket's Piece is a secondary weapon in PAYDAY 2, added with the release of Hotline Miami 2: Wrong Number on Steam. Ownership of the Digital Special Edition of Hotline Miami 2: Wrong Number on Steam is required to access this weapon in-game.
This Overview mostly apply to the console versions, as most of these stats have been changed on the PC version:
The Jacket's Piece can be considered somewhat of an altered Mark 10, with a few advantages (and disadvantages) over its counterpart in a toss up.
For starters, the Jacket's Piece has a lot more available ammunition (almost 50 more rounds) than the Mark 10 despite the smaller magazine size. Its rate-of-fire of 1,200 means a higher DPS than the Mark 10. Lastly, it has substantially less recoil due to a better Stability rating.
The Mark 10, however, is more accurate at longer ranges (despite both having horrible base accuracy), the ironsights on the Mark 10 is also clearer and easier to use, is more concealable and reloads much more quickly. Its lower rate-of-fire and bigger magazine means that outlasting the Jacket's Piece is not a problem magazine-wise. It is also available almost right off the bat in the base game and for a dirt-cheap price.
To sum it up, the decision between bringing a Mark 10 or the Jacket's Piece is entirely a matter of preference. Both weapons have the same damage rating, though the Jacket's Piece can be modified to a greater extent than its rival, and thus will have more of an edge during combat. It is only available, however, if the player also has the Digital Special Edition of Hotline Miami 2 linked to their account, which is another point to consider.
Despite having one of the fastest tactical reload times in its class, at 4.3 seconds a dry reload of Jacket's Piece is second in tedium only to the Chicago Typewriter. Even with skills enhancing the reload speed, emptying your magazine should be avoided if at all possible. It would be more effective to reload frequently with a partial magazine than waiting until the weapon is empty.
With SMG Specialist aced, the Jacket's Piece can attain an absolutely monstrous rate of fire, an even faster reload and an extremely high damage rating. This allows it to be used even more aggressively with little downtime between magazines, at the cost of an even more rapid ammo consumption.
Acing Fully Loaded both grants the player an extra magazine to use while remedying the weapon's horrifying ammo burning rate.
Though it has very low accuracy when being fired at full-auto, it does have decent accuracy when switched to semi-auto.
However, adding the "single-fire" mod can be considered counterproductive as the main advantage of the Jacket's Piece is the extremely high rate of fire.
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.
Despite the website saying the Jacket's Piece is a modified Mark 10/MAC-11, it is actually an SWD/Cobray M11/9, a semi-automatic civilian version of the MAC-11 that can be told apart by its elongated receiver. The weapon is additionally modded with an aftermarket foregrip that also doubles as the barrel nut housing.
The Jacket's Piece also features two of the barrel designs of the Mark 11 from PAYDAY: The Heist as its Barrel Extensions. The Werbell's Suppressor was based on the default suppressed barrel of the Mark 11, while the Slotted Barrel Extension was based on the Lightweight Suppressor upgrade, albeit (realistically) without any noise suppression this time around.
As it was based on the M11/9, the in-game weapon was modded to be able to fire in full-auto.
Despite being a(n illegally converted) machine pistol, the Jacket's Piece is classified as an SMG in-game.
It is rather odd for a gunsmith to include a selective-fire block when converting the weapon to full-auto. In addition, the tacked-on selector dial has a setting for an "SMG" mode, whatever that means, and this is also in the same position as the "Safe" notch on the other side of the gun.
Even more peculiar, is the fact that the Cobray M11/9 fires from a closed bolt, while Jacket's Piece visibly fires from an open bolt, which would have required an extensive modification beyond simply converting the weapon to full-auto or select-fire.
The Jacket's Piece is compatible with CAR-type stocks. This makes it the third SMG/machine pistol capable of mounting such attachments and the second non-AK, non-CAR secondary weapon to accept these stocks, after the Locomotive 12G.
