ive been trying to figure this out actually, but you can fix the pickup animation by changing the setting in FDDA for pickup distance to .3 or .5, but so far have not been able to fix the pickup sound on mag reload.
tried removing the pickup sound for magazines, and although it worked for making magazines moving in your inventory silent (not really the goal, but proved it worked) the sound still played, so it's some other interaction thats causing the sound
