Holding F to drop a weapon?

in a tense situation of dumping your last mag so to say it'd be nice to be able to hold F to drop your gun/whatever your holding to lose the weight of it off your character. Thoughts?

should be triple F to avoid triggering players with fat fingers. after all, F is right next to the WASD buttons

Yes it would be cool if you could drop your weapon to lighten the load!
