At least one of the gun types from Modular Turrets, the Heavy MG (the thermal laser can be placed in a grid, but i don't think it can be used as a normal gun, though i haven't gotten far enough to check that one yet) can be used as a player-held gun as well as crafted into a turret like normal. However, when I try to place the Heavy MG in the bandoleer instead of in a normal gun slot, it says "This item is restricted from being put into this container item." and won't let me. I'd like to request you add compatibility to place that gun in the bandoleer. Alternatively, give us a setting to override the restriction and either unrestrict the slots or whitelist items manually.
