Code of Conduct: A paladin must be of lawful good
alignment and loses all class features except proficiencies
if she ever willingly commits an evil act.
Additionally, a paladin’s code requires that she respect
legitimate authority, act with honor (not lying, not cheating, not using poison, and so forth), help those in
need (provided they do not use the help for evil or chaotic
ends), and punish those who harm or threaten innocents.
"coppied from the CRB"

Act with honor (not lying, not cheating, not using poison, and so forth)

after looking at a few Paladin builds im finding this increasing trend for paladin archers.

Its in common lore that it is dishonarble to use a bow against a knight or worthy oponent.

IE a knight may not shoot a bow at another knight but must meet him with lance or sword.

A peasant may not shoot a knight with a bow for he is a lesser. "unless the knight carries a bow of course"

So under chivalric law, wouldnt a Paladin useing a bow against a non ranged oponent be violateing there code of conduct?

Edit/ added
1130 The Church banned bows and crossbows as immoral weapons not to be used against Christians. Knights considered the weapons beneath them
