Are guns considered physical weapons?

Hi everyone, quick question: are guns considered physical weapons?

I am currently running "The disintegrator" from the Pulp Cthulhu rulebook, and in Mr Sleep's armor section it is written that "physical weapons do only 1 point of damage per hit", and I was wondering if you would consider all physical weapons, including any type of gun, or only blunt and slashing weapons (knives, bats...).

I think I am going to answer yes to the question, because I want to play a scene where one of the other NPCs shoots at him with a gun and it miserably fails (1 point of damage per round, assuming a single shot, vs 2 HP regenerated per round), but I wanted to ask anyway, to see if anyone has a different opinion.

Thanks!
