Actually, I differ on that.
With a hoarder build, you will usually be able to reload between areas, you also get a free reload each time you enter gunzerk and if it’s REALLY an issue for you, a single point in auto loader would fix any remaining issue.
Don’t forget that 6/5 FttB in a bandit gun will make it hold sometimes half your total ammo.
And you still have incite… And keep firing… And Inconceivable… And 5so6…
Bandit shotguns are garbage on hoarder builds anyway: the good ones use too much ammo to benefit from 5so6, and their spread at max accuracy is horrid.
The real closest thing to a Vladof shotgun are the Hyperion ones
