I tried using the keybind for....I forget, essentially Last Weapon....and it'll work great for Medtool to Rifle, but when I hit it again, it pulls up my pistol. Did I miss an option in the Keybindings, or can we seriously not quick switch between Rifle and Medtool?
Have you tried rolling the mousewheel and pressing to select, to see if that is any faster? I only know that it will switch from knife to other weapons and medkits myself.
