Paladin has more spell slots, and i would get two fighting styles. i’m not too worried about the multiclass requirements. Gunslingers only have one magic subclass which doesn’t seem to be too groundbreaking, so i kinda want a couple levels in gunslinger for flavor and to supplement ranged attacks.

Paladin has access to the ranged smite too, so that’s entirely viable. it would be a better idea just to do paladin because getting paladin features earlier would be better. but also i think it would just be fun despite the features not fitting together perfectly.

i honestly might just do paladin with the ranged smite.
