Just going to toss out a couple unusual topics I have encountered during training. Perhaps you have tried this, if not it might be worth trying.
The behind the scenes story… It was an early morning headed out to an advanced 8 hour pistol class where we would shoot between 500 and 750 rounds during the day. A friend was taking the class with me and we stopped at the paper box to grab the paper as we were leaving. I was promptly bit on my right hand 4 times by some PO’d yellow Jackets… and I am allergic. My right hand swelled up to 3 times its size, didnt need an epi-pen and wasnt going to miss the class I had been waiting for for 4 months.
The instructors had me shoot the entire course left handed using my right eye for sighting the entire day. I did really well to my great surprise. "The instructors were great, said as long as uou have the sights lined up you will hit the target. Pistol dosent care which hand it is in"
I had never really thought about it before. I had done left hand shooting before and it was ok but also tried using my left eye and it was awkward.
Never know what condition you may be in and end up having to defend yourself. This really sunk in to me. Now I practice this left hand right eye shooting at least a bit every time I shoot.
