Need help fixing my grab script

Hello guys! I have pretty simple grab item system that allows me to grab item, put it in slot and trigger event. But i need to make the script acting more stable.For example - when i grab an item, i need the item in the hand to stay still or freeze because otherwise it causes some weird glitches when item interact with rigidbody attached on FPS controller.
Here is the glitches example -

EDIT: I cannot post script because it is flagged for spam


Many Thanks!

 

One possibility is to just crank up the damping setting of the Rigidbody on that object until it doesn't flap around so much...

 

I tried to increase mass on the rigidbody but it doesn't seems to help.Other problem is sometimes the item just goes underground.I really don't know why i cannot paste the code here.I know blind help without the script is hard. Thanks

 

Don't increase the mass, increase the damping, or

.drag

. Probably jack up the

.angularDrag

too.
