As usual, here's how the new event weapons look like when equipped.
The following images were taken as equipped by a lvl 60 Fighter wearing a Working Class man (+5% Reload Speed, +5% APS) plus a Terror mask (+10% Hit Chance, +10% Damage) for the SMG and a Blind Justice mask (+5% Reload Speed, +5% APS) for the other weapons.
Also, the following gear was used:
RS: Commando gear with +55.8% Damage, +90% Reload Speed and +84.5% Ranged Combat
DMG: Commando gear with +60.8% Damage, +70% Reload Speed and +107% Ranged Combat
COMM: Commando gear with +65.8% Damage, +87.5% Reload Speed and +102% Ranged Combat
HOLST (pistol only): Holster with +100.7% Damage and +91.3% Reload Speed
