Hit Thresholds: Each Investigator has a Hit Threshold of either 3 (the standard value) or 4 (if the Investigator’s Athletics rating is
8 or more.)
The Hit Threshold is the Difficulty Number the Investigator’s opponent must match or beat in order to harm him. Less competent NPCs may have lower Hit Thresholds, but cult guards, Gestapo agents, and similar opponents will generally parallel Investigator levels.

Danni:
For firearms, add an additional +2 when fired at point-blank range.

f you are at the mercy of an opponent with gun well in hand and ready to fire, he can empty his entire clip or chamber at you before you get to him, or get yourself out of range. This situation occurs for example, if he holds you at gunpoint or charge him from more than five feet away with no cover.
The Difficulty is 1 (an automatic hit), 2 if your Athletics rating is 8 or more and you are moving. He rolls one instance of damage, which is then tripled. Yes, we said tripled. And, yes, the tripling occurs after weapon modifiers are taken into account. This is why few unarmed people attack a gun-wielding opponent when he has the drop on them.

If your opponent has a pistol but it is not well in hand and ready to fire, you may attempt to jump him and wrestle it from his grip. If he has a pistol well in hand but is unaware of your presence, you may also be able to jump him, at theKeeper’s discretion. The characters engage in a Scuffling contest to see which of them gets control of the gun and fires it. The winner makes a damage roll against the loser, using the pistol’s Damage Modifier, including the +2 for point blank range. If you jump an opponent with an unready rifle, a Scuffling combat breaks out, with the opponent using the rifle as a heavy club.

Fighting Without
Abilities
A character with no
points in Firearms is not
allergic to guns. The most
neurasthenic and mollycoddled
aesthete is able to
pick up a revolver and empty
it in the general direction
of the foe. Likewise, a
character with no Weapons
ability is not going to just
ignore the fire axe sitting
on the wall when the
ghouls come up through the
floorboards. Even a mere
slip of a respectable girl with
no Scuffling score will try to
kick or even bite her vulgar
assailants.
However, such characters
will use their weapons
ineffectively and hesitantly.
Using a weapon (including
fists or feet) without ability
has the following drawbacks:
- You automatically do
an additional -2 damage.
(Keepers may suspend
this penalty for maniacs,
who always seem to do
exceptional damage with
improvised weaponry.)
- You must declare your
action at the beginning of
each round and cannot
change it if the tactical
situation alters.
- You automatically go
last in each round.
- If you are using a
firearm, a roll of 1 means
you have accidentally shot
yourself or one of your
allies, as selected (or rolled
randomly) by the Keeper. Do
damage as normal (including
your automatic -2 penalty).

Chi non ha l'abilità Uso Armi da Fuoco:
- You automatically go
last in each round.
