my vault isn't full, because I keep all my character weapon slots full the reason I do this is so the weapon drops from raids etc go direct to the postmaster in my case, I have 17 weapons in my vault, and 16 weapon items in my postmaster across the 3 characters i've also sharded a load of weapons I'd have liked to keep (strangers rifle for example) having no character weapon slots free means I don't pick up green weapon engrams, so my stock of weapon parts is depleting over time EDIT: you might call me a packrat, but there is method to it. I used to have all the VoG weapons on each character fully levelled (corrective measure, vision of confluence etc), as they're my go to guns. I sharded the duplicates due to lack of space, and now keep 2 unlevelled duplicates for each across the postmasters in case you guys let us upgrade them in the future.
