Double-Barreled Firearms, how do they work?

[Ssyvan]

Specifically I have a player using a Double-Barreled Pistol which says:

PRD wrote:

Pistol, Double-Barreled: This pistol has two parallel barrels; each barrel can be fired independently as a separate action, or both can be shot at once with the same action. If both barrels are shot at once, they must both target the same creature or object, and the pistol becomes wildly inaccurate, imparting a –4 penalty on each shot.

That was fine until I saw the Double-Barreled Musket which says (bolding for emphasis):

PRD wrote:

Musket, Double-Barreled: This musket has two parallel barrels; each barrel can be shot independently as separate attacks, or both can be fired at once as a standard action (the attack action). If both barrels are fired at once, they must both target the same creature or object, and the gun becomes wildly inaccurate, taking a –4 penalty on each shot. Each barrel of a double-barreled musket uses either a bullet and a single dose of black powder or an alchemical cartridge as ammunition.

I'm wagering this was an intentional discrepancy (unless someone can point out otherwise), which means that the Double-Barreled Pistol can fire each barrel at once as part of either the Full-Attack or Standard Attack actions?

I also want to clarify this point. It says the both can be shot at once with the "same action." Does that mean if I'm a 6th level Gunslinger and I take the Full-Attack Action and I chose to double fire my attack array would go from +6/+1 to +2/+2/+1? And more importantly that I'd be unable to Double Fire on my iterative attack?

So to recap:

-Can the Pistol be double fired as both a Standard and Full-Attack Action?

-Assuming it can be double fired as part of a Full-Attack action, I only apply the -4 Penalty to the split shot and *not* to the iterative attack.

-Most Important. I can only split one shot per action? Which is not the same as splitting any shot I fire.

Also, can you use Double Fire on an Attack of Opportunity?

An AoO is a "single melee attack" assuming they have snap shot it would still be a "single ranged attack".

Also, is an AoO considered an Action for the Double Fire rules?

These were errataed (?) not too long ago.
The language should be the same for both now (the musket one has been updated properly the pistol wording is wrong)

ie: using both barrels is a standard action

This was primarily to avoid all the gun shenanigans that used to occur with folks shooting both barrels for every attack during a full attack actions.

So in your example, you would lose your iterative attack (as you can't full attack anymore firing both barrels) but gain the 2nd bullet ... so +2/+2

Unsure what happens if you misfire on both ... =) kaboom?

i believe you are mixing different printing of the same book. Originally double barreled fire arms could exactly double your attacks per round so long as you found a way to reload as a free action. That was very easy to do with alchemical cartridges and some archetypes of gunslinger. this combination was very controversial and eventually the books were errata'd to change any double fire arm into a standard action to fire both barrels at once.

As to an AoO, if firing both barrels is a Standard Action than you can not use both in an AoO as that is a specific attack and not a more generic chance to use a Standard Action.

Ah, okay, I'll see if I can dig up that errata. Thanks!

It is on this site even, http://paizo.com/pathfinderRPG/resources

Top left of your screen, there should be a Pathfinder Roleplaying Game heading with "Free Downloads" listed under it. the one you want is highlighted in red still as it is the most recent.

[Ssyvan]

Yeah, I just read it, but that only changed the Double-Barreled Musket. It seems nothing was changed about the Pistol...

What was the old language for the Musket?

[EvilMinion]

The musket and pistol used to say the same thing (what the pistol does now)

The errata changed the musket wording, but they forgot to change the pistol wording.

There was a later clarification that the pistol was supposed to change as well in the same way.

[Torbyne]

ah, the Errata to the Errata. yes, is that on the FAQ Page somewhere, or in the Errata-FAQ-Errata-FAQ sub resource downloads somewhere?

Keeping track of PDT posts that correct corrections can be a chore but going off hazy memories of something you read on the forums can at least give you some guidance for rulings at your table. :/

I know you're being sarcastic, but that one IS on the FAQ page.

I was but that is very nice of you to post, thanks!

[Ssyvan]

Thanks all! I see that now!

So...
If att a BAB of +6/+1 you could use two Double-Barreled pistols to get an attack of +2,+2,-3,-3.
(Fire one DB-Pistol, drop it, draw second DB-Pistol, fire it)
Where the +2 attacks must attack one target and the -3 attacks can attack the first target or a second?
Or...
Can you only get a MAX two attacks? +2,+2 losing your -3 attacks
So may as well stick to single shots where you get+6,+1?

[nicholas storm]

+2,+2 losing your -3 attacks

[Jeff Merola]

As they currently stand, if you can full attack you should full attack normally. Only use the two-for-one shot if you had to move (or otherwise use your move action), and thus can't full attack anyway.

Ok, here's what you can do with a double-barreled gun:

As a Standard Attack Action, you can fire both barrels with a -4 penalty, rolling for each one. You get two shots, but only on your Attack action (Neither Full-Attack nor AoO is the Attack action). Or you may make a full-attack and make your normal attacks with the benefit that you reduce the impact of reloading. With a single-barrel gun, you fire once, reload, fire again. With a double-barrel gun, on a full-attack, you fire twice (BAB+6, then BAB+1, no -4 penalty), then reload either one or both barrels. In other words, you don't consider each potential attack within a full-attack to be an Attack action and subject to the "doubling" effect.
