'best' stance for self defense with a handgun
What ever stance you are in at the time.
Laying on your back after getting knocked down at the ATM
Inside your car during "carjacking"
Setting at a table in a resturant
Setting on you recliner during a home envasion
Standing up with a bunch of goodies while in line a a convience store
Laying in bed
The list is unlimited, but as you can see from the partical list the need to practice one handed.
I believe a min. of 90% of your shooting should be one handed, 60% weak hand, 30% strong hand.
