That's not sissy acrobatics. Training to fight comfortably from any position and being able to move to and from those positions fluidly is more important that you seem to think.
Try shooting with one hand. Try running while shooting with one hand. Try shooting with your weak hand as your strong hand. Try shooting with only your weak hand. Become ambidextrous with your pistol, your rifle, your movements, and train until you're comfortable doing so and fluid in your transitions. Then train some more.
You don't know what you don't know.
