Well I’d rather it not be a gun, but if it HAD to.

Blade would be double edged, maybe with a spike on the pommel. It would have a rifle barrel run down the middle of the blade whch you can fire while doing stab motions (maybe even let the grip curve so you can aim it like a gun). And through folding frames it could turn into a spear, at which point the blade bisects into 2 piece and assumes a scythe shape except with 2 blades.
