protip: use your combat/reg pistol on computer and your ap pistol on online players so your ammo wont burn out so loving fast
i like using the SMG towards AIs because of it's reliability and that it's automatic, i only use the Combat Pistol towards AIs on the first round of Survival.
the pistols are a great way to get headshots on Online players though
Pistol and pump shotgun vs regen half-health, aks, body armor, and maybe rpgs.
too bad body armor didn't exist (or atleast was in public use) in 1911!
