ADS Sensitivity is not the same on all Guns

I never took this into consideration until i read this thread and really thought about this and played a couple games to test it out, it always felt something wrong about aiming in Apex Legends and why it's so inconsistent. I can confirm now that ADS sensitivity feels different on multiple guns and FOV is also really bad on some of them, i find myself desperately looking for scopes many times, because i can't see and track my enemies when i shoot them without a scope. Now i finally found out why my aim is so sluggish and inconsistent in Apex but perfectly fine in all the other shooters i play/played even from the start.
