The game operates with the heister moving in with 2 weapons, and 2 weapons only. A primary and a secondary. Primaries consist of assault rifles, shotgun, and marksman rifles. Secondaries consist of pistols, machine pistols, and bizzarely, a few chopped down variants of some shotguns and assault rifles. Players can take ammo from enemies, but not weaons, ala SWAT 4 and other such tactical shooters.
Primary Weapons
Colt Model 733
The Colt Model 733 is the first primary weapon unlocked. It's choices for modifications are very limited.

Note, the Model 733 does not appear to have a set specification from Colt, and could be found with either an A1, A1E1 or A2 upper receiver, A1 or A2 lower receiver, and a coated aluminum or fiberlite stock. This particular rifle has an A2 lower, an A1E1 upper (forward assist and case deflector with A1 sights as found on Canadian Colts), and a coated aluminium stock.File:PAYDAY2-CARBINE.jpgThe 733, in high res glory. Fairly familiar?
AKS-74
The AKS-74 is the second primary weapon unlocked. It's stated as being chambered in 5.45mm.
The G36KV is the seventh primary weapon unlocked. It's equipped with a G36C carry handle by default. It's folding stock makes it slightly more concealable than most long arms.
The Saiga 12K appears as the ninth primary weapon, and the only semi-automatic shotgun available. It has the folding stock of an AKMS, for some reason.
The Glock 17 appears in-game as the Chimano 88 Pistol. It is the default secondary weapon, and can accept very few mods, limited to barrel extensions, like suppressors.
The MP5A2 is the sixth secondary weapon unlocked, and is the first full-sized submachine gun.

Remington 870
A stubby variant of the Remington 870 is available as the seventh weapon unlocked. A considerable cut down on the long variant, it makes a great, if obvious sidearm.
The Olympic Arms K23B Tactical is available as the eighth secondary weapon. It comes with a wire collapsible stock, and a slightly longer handguard that covers the gas block.
A variant on the AKMSU is the tenth secondary weapon to unlock. It has the folding stock of an AKMS, but the short barrel of the AKMSU.
