Yes, DireRanger50 is right: this feature was intentionally left out because re-equipping was really complex to code and test even with melee weapons. With ranged weapons it would also need to switch the type of ammo the NPC uses, and how the AI works, among other things. So, I'd say expect it in a near future update.
