This is why I practice shooting with one hand.
At the range I shoot mainly with both hands but also do speed drills with each hand individually. Not target shooting but strictly tactical, my accuracy suffers some but I know I can blow out a center of mass with either hand.
Yesterday I was working and I slipped with a tool and punctured my left palm, it went deep enough to need hospital attention, it's now stitched up and bandaged. It's my weak hand but it is still a disadvantage.
However, I have practiced for just this. I know that I can carry today.
If you don't practice one hand shooting then let my accident be a pointer for you.
And yes, I am having a bad run presently. I had to have a root canal done while on vacation in San Francisco last week and now this. Maybe bad things won't come in three this time, but if they do I'm ready for whatever.
