Every once in a while in our IDPA matches someone will make a scenario that you have to draw and fire your gun with you weak hand.
It is always interesting to do and interesting to watch what others do.
Just the physical requirements to safely draw your gun from your strong side with your weak hand is something that requires effort and practice.
It would behove anyone that has not done this to try it as dry practice at home.
It can be done very safely and quickly but not if you haven't done some practice at home.
