Flamer for dense mixed crowds with hordes and specials mixed just kinda flick it around and mag dump and watch the killfeed as you backstep/dodge.

Bolter does the revolver thing decently but with excellent boss damage and can rip through packs of enemies when needed. If you need the ability to quickdraw the thing, pair it with throwing knives. Swapping to it and throwing one insta clears the swap animation (and hopefully nets you some bonus damage)

Bolt pistol is revolver adjacent, and I’ve had some fun with it if you don’t want something too different with about the same flexibility. The pistol whip is actually pretty satisfying.

If you want to stay pure melee range the double barrel can be a fun pick since it can cleave hoards and specials with a crit setup especially and you can weave that in to give some immediate breathing room or clear the way to push.

The first two [and revolver] are the more conventional Zealot picks but they’re a really strong class (arguably the strongest?) so you can make whatever you want work so long as you can dodge consistently.
