On December 1st, the day I wrote about shooting left-handed, my brother Deejo blew out his right biceps tendon.
I'm not the only one in my family who believes we should be competent shooting with both hands, though I'm the one who practices the most (and probably the one who needs the most practice).
Knowing he would be off work for a while - it's hard to drive a 36' truck with a manual transmission once you've ruptured a bicep tendon - he called up and asked if we could go shooting. Only in my family would we find an injury reason to hit the range, but his work injury is the exact reason everyone should practice and become competent with their non-dominant hand.
Trust me, he did not go into work on Friday morning looking to suddenly become left-handed, but shit happens and until he's healed up from surgery and finished with his physical and occupational therapy, left-handed he is.
If you've been putting off your non-dominant hand practice because it's "uncomfortable" or "awkward" stop making excuses, get off your butt, and get to the range. This isn't like PE in junior high, where you get hurt, wave your hand, limp off the field, and get left alone. Outwardly injured folks may look even more enticing to a predator; why would anyone just accept that fate? Refusing to become competent with your non-dominant hand puts you at even more of a defensive disadvantage.
