The fastest-killing sidearm in Wardogs is the GGX 18 — ranked here by measured time-to-kill across every sidearm in the game, with the reasoning and the full board below. Fastest TTK, not an unqualified “best gun.”
The best sidearm loadout in Wardogs right now is the GGX 18. It posts the fastest measured time-to-kill of any sidearm in the game -- about 287.2ms on a balanced profile, 103ms clear of the Deagle, the next-fastest.
That order comes from scoring 5 sidearms on measured time-to-kill from community ballistics testing -- not on feel, and not on a spec sheet. The numbers come from more than one attributed data set (each weapon is tagged on the board), so compare across data sets with care.
