Equipment is generally only damaged when targeted. Otherwise, it's a non-issue.

Some GMs will include actual damage to equipment, but that's when they're going HARD for realism, or punishing their players for some reason or other

It's also the case that in 3.5 and related systems magic items are treated quite differently for how they can be destroyed. Many things that destroy mundane items have no effect on magic ones, or at least offer a save where there would normally be none.
