I like the TFWPKY for PvE, its a nice 331. My favorite 331 PvE handcannon right now is the Venation (Dead Orbit, I think). It's quick and hit pretty hard. I used it during our last VoG hard run; one crit hit goblins and hob-goblins, two hit harpies, did surprisingly well against the oracles. Full disclosure, if Fatebringer was a 331 I wouldn't use any other hand cannon in PvE, but its not. I'm holding out hope for the Crota hand cannon, but we need to beat it on hard before I have a chance at that.
