One-handed double weapons (Dagger pistol and sword cane pistol)

Each of these weapons is declared to be a combination of their respective melee weapons and a coat pistol, and the stat-blocks in Ultimate Combat gives the normal coat pistol damage/range/etc. How would TWF penalties be calculated for a double-weapon that is wielded entirely in one hand?

The standard for double weapons is as if wielding one one-handed weapon and one light weapon, so how does that resolve against a one-handed weapon (firearm) and still having a free hand?

The dagger pistol is considered a double weapon for the purpose of creating masterwork or magical versions of this weapon.

It's not a double weapon it is just treated like one in terms of cost, so no TWFing with just one. There is a one handed double weapon but it is still held to the rules for TWFing with a double weapon.

Double Weapons: Dire flails, dwarven urgroshes, gnome hooked hammers, orc double axes, quarterstaves, and two-bladed swords are double weapons. A character can fight with both ends of a double weapon as if fighting with two weapons, but he incurs all the normal attack penalties associated with two-weapon combat, just as though the character were wielding a one-handed weapon and a light weapon.

The character can also choose to use a double weapon two-handed, attacking with only one end of it. A creature wielding a double weapon in one hand can't use it as a double weapon—only one end of the weapon can be used in any given round.

So you would have to use the one handed weapon with both hands to use TWFing with it.

Dang, thought I had a good QCF build potential with Deft Shootist and the usual finesse and ranged feats.

Do the dagger and sword cane portions of their respective pistols still deal their usual damage and have the preexisting crit ranges and multipliers?

Realisitcally life would be simplier for those weapons if they just declared them to be double weapons..

As it stands you pay for it as if it was a double weapon, but honestly get almost none of the benefits for it. Currently the dagger pistol, if the pistol part breaks then the dagger breaks too. (though the sword can pistol doesn't have that wording last i looked). So it just costs extra without actually any major benefits..

So you have to pay for each side's echanment seperately, but you can't use them seperatly in anyway.

They really should alter these to just be double weapons. It would simplify the hell out of things..
and allow all the cool gunblade builds and RWBY builds people want to do sometimes.

Instead of the gray area issues that keep coming up. Like below

On to the actual question above
The weapon doesnt' really address what each part of it's damage does..

so I guess techicallly it does the listed in the blcok. So both the pistol and the bullet does the same damage amounts. 1d4. 3x. 10ft

Though honestly if this isn't pfs ask if you can use the dagger side as if it was a dagger. I"m pretty certain that was the original intention, due to the wording in th description about "used as both weapons" However because it isn't specifically declared, you have to use the stat block presented.

another reason they should just change the entry to fully to a double weapon, then it could either list the two weapons on the table as per normal double weapons, or the description could specifically site "use the dagger as per the melee weapon and use the pistol as per coat pistolk without the bonus to slight of hand"

You could just dual wield them and be the master of gun-knife fu or something?

I'm sure there's a rule saying not to somewhere, so why can't you make your attack with your main hand and free action switch to your off hand to make the two weapon fighting attacks.

Yeah, they need updates, along with the warhammer and axe musket variants. Although at least those, as already being two-handed weapons, make the TWF questions a bit simpler. Although with those, they dropped the firearm damage down to the level of the melee weapon damage. *facepalm*

Because then I'm taking the full TWF penalties for a pair of one-handed weapons, for only dishing out piddly d4's with no expanded or multiplied crit.

Two-Weapon Fighting

If you wield a second weapon in your off hand, you can get one extra attack per round with that weapon.
