practice one hand only shooting
You may well need the ability to shoot strong hand only or weak hand only in real life. You'll for certain need those skills if you shoot IDPA or IPSC/USPSA matches.
I shot in a USPSA special classifier match last weekend. There were 5 stages. Firing with strong hand only and weak hand only was required in 3 of the stages.
I didn't do as well as I should've -- I hit a "no shoot" target shooting weak hand only and missed two headshots, one strong hand only and one weak hand only, but other than that things went okay.
I practice shooting one hand only all the time, so I should've done better.
You can only learn from experience if you pay attention!
