I want a shotgun cestus

[Kazaan]

We've got dagger pistols and axe muskets. In honor of RWBY Yellow, I want a shotgun cestus. Someone needs to get on this ASAP.

Seems more of a houserule thing, but I'd like some more gun-kata type stuff. I always saw gunslingers as the flashy fighting type anyway.

Problem is, weapons in PF aren't too much more than statblocks.

I would suggest something like take a normal Cestus, add about half the weight of a Shotgun, then double their combined prices and maybe add Masterwork on top of that.

Definitely counts as an Exotic weapon. Add the following feats:

Blast Punch --
Prereq: Weapon Proficiency(Blast Gauntlet), Weapon Focus (Blast Gauntlet), Improved Unarmed Strike.
Benefit: Allows you to trigger a shot from the Gauntlet as a free action upon connecting with a melee attack.

Recoil Boost --
Benefit: By discharging a shot from a firearm, Increase your movement by ten feet per the firearm's damage die.

Also regular and blast punch attacks should probably include the misfire chance of firearms. It can not be good for a firearm to be subjected to repeated blows.

Alternatively, just interpret the pistol whip of a shotgun, wielded as a two-handed melee weapon, in concert with a buckler as a shotgun cestus.

I am wondering how this weapon would work.

This is the concept

In game, I'd just make it a large dagger-pistol that does bludgeoning instead of shlashing/piercing.

Also, I have made this feat a while back that seems relevant now.

How about the Ballistic Fist.

At least thats what I immediately thought of. How you mechanically represent that is up to you.
