Armor pen is an elemental damage type in the game so...

normal weapon with no mods say 10 damage per shot = 10 x300% = 30 damage

now normal weapon + AP mod at say 30% so you would get 10(normal) + 3(AP) damage so it would work out to 10x300% + 3x 200% = 36 total damage.

so you still deal more damage with AP mod than without.
