Firearms - Deadshot vs Iterative Attacks

[Backlash3906]

Can someone give me a pluses and minuses of either option? Assuming reloading has already been handled (either via pepperbox or revolver, or other shenanigans).

For reference:

Thanks! :)

Iterative > Dead Shot

Cons of Dead Shot
Dead shot doesn't add together all your potential attacks (you loose haste and rapid shot attacks).
You don't add a lot of your modifiers more than once (like precision). This can be a big LG damage pool.
Costs a grit or signature deed.

Pros of Dead Shot
Nearly no chance of a misfire
If you crit, it's extra dangerous.
Less ammo expended (which is pricey for gunslingers.)
Clusters damage together for the purpose of overcoming dr.

I prefer Clustered shots. The only thing that would really make me consider dead shot is the ammo cost, as 6 GP'S a round is cheaper than 24 (Assuming rapid shot and haste) when this comes online. But the loss of 2 of 4 attacks is huge.

I could see Dead shot being useful if your in a long dungeon crawl and start running low on ammo i guess.
