Occasionally when I am using an assault rifle with grenade launcher attachment, if I briefly switch from the assault rifle to a throwable grenade like frag or incendiary with the "3" key, when I press "1" on my keyboard it switches back to the grenade launcher, despite this same button usually switching back to what I was using before, the rifle. I only use the number row to switch weapons, never the mouse wheel.
This isn't just an issue with the AKM, it has also happened on the M16A4, and this has definitely happened to me multiple times throughout all game versions.
