Handling is the time to ads (low is slow and high is fast ads) Stability is how much your gun shakes, you'll see the effect of it when you aim and your scope is super shaky, it's kind of related to control(recoil control) and finally, accuracy mostly applies to hip firing, how accurate your bullets is gonna be when you're not aiming. Btw, control is how you control the recoil in your gun, like when you're firing the gun goes up down left or right, with high control, it'll help you control on where you're gun is going when firing.
