The original ring hand figures had their hands in a literal ring shape. It was hard to get weapons in their hands.
This carbine has had the sling cut off so he can hold it. Later, many of my ring hands got one or both hands slit open so they could grasp items better.
This guy is a slot hand figure, the hand has a slot and the weapons are sort of slipped into the slot.
This guys lower hand has been cut.
Similar figures but the accessories really make them look different.
