Yes, but you also have to consider the type of ammunition and pistol being used.

While whale-oil powered, the guns have very similar designs to flintlock pistols. Depending on its make-up, a flintlock (even at close range) may not be able to penetrate treated plate armor that had been proofed against firearms.

Finally there is the fact that the weapon Corvo (or Daud depending) is a pistol as opposed to a musket and therefore might not have the effective velocity to penetrate the mask.

Even so, repeated shots could/should have cracked or at least dented the mask - you are VERY right about it being serious material. :)
