Which weapons count as a shotgun in Fallout Shelter?

Question

I've got this objective:

Equip 2 Dwellers with a Shotgun

I tried equipping with Enhanced Sawed-Off Shotgun, Sawed-Off Shotgun and Rusty Combat Shotgun, but none of those work. For the Equip n Dwellers with a weapon objectives, it's enough to switch out the weapon for a fists and back to the weapon, but here that doesn't seem to work.

Which weapon do I need to use to fulfill this objective?

Answer 1

Here's a partial list of weapons and their type.

As Jason Berkan commented, the fastest way to complete that kind of objective is to find a dweller without the type of weapon required and equip them with one. If you don't have a spare weapon of the type needed in your inventory, unequip one from a dweller with a weapon of that type, find a dweller without that type of weapon and give them the weapon.

In your case, the type is a shotgun but this applies to any objective requiring to equip an armor or weapon type. Also, beware that Sawed-Off Shotgun and Combat Shotgun are types of their own.

Shotguns are

1. Rusty shotgun
2. Shotgun
3. Enhanced shotgun
4. Hardened shotgun
5. Double-barrel shotgun
6. Farmer's Daughter
