First Leaping Shot Deed says the following, but...
Leaping Shot Deed (Grit)
You leap through the air, guns blazing.
Prerequisites: Dex 13, grit class feature or Amateur
Gunslinger feat, Dodge, Mobility, base attack bonus +4.
Benefit: You gain a +2 bonus on Acrobatics checks made
to jump. As a full-round action, you can move up to your
speed and make firearm attacks at your highest base attack
bonus with each loaded firearm you are wielding. You can
make these attacks at any point during your movement,
and if you are wielding two firearms, you can make the
attacks at different points during the movement. At the
end of this movement, you fall prone. This deed costs 1 grit
point to perform.
If you are using 1 gun can't you already fire a single shot at your highest base attack and make a full move as a full-round action or is this feat/grit only worth having if you are using 2 guns? I'm trying to find the value of this feat. Thank you for any help trying to understand this feat.
