Slinging weapons
This idea/suggestion is Open. You can respond to ask questions or discuss the idea and either vote it up or down if you believe it should or should not be implemented, respectively. Popular suggestions and ideas will be considered by the development team to become reality in-game.
Proposal
Immersion would be better, instead of running around with your weapon in hand all the time.
Justification
Immersion, and it would be good to do so.
Motivation
Make it more harder to detect or see who is potentially hunting you. And just a better look overall
I think slinging any weap in the game would be a good idea for a functional action, and have a designated key for such thing, for instance, Z or X would a good one. You hit it, and you sling and unsling the weap.
