Title says it all. Excellent game, well made, actually feel like I'm looting all the cars on the freeway and love it. I am about 30 minutes in and have found 4 guns. How on earth do I DROP the gun I don't want? All I can do is swap the guns when I reach out to get the other one. I've tried holstering but then it just swaps. Can someone tell me how to do this or what I'm missing?
