Yes.
Mostly 2 points, sometimes 1 point when I use SMG or very short rifle. I use a clone Magpul MS2 sling so I can switch between 1 and 2 points with the same sling.
When standing, I sling my primary when using pistol. When I am crawling, I just put it to the ground.
When I walk to/from spawn point, depends on the size of the field and the distance to the fighting zone, I may also sling my primary weapon.
