I never made myself practise shooting weak side enough, until recently.
The way I did it was to run my trigger finger into a bandsaw and cut it to the bone from the 2nd nuckle out to and thru my nail.
Needless to say that if you can't get your finger on the trigger and can't bend it anyway, it creates a problem when carrying.
I have been shooting with my "other trigger finger" for several weeks now and am seeing definite improvement.I hope to get back to shooting normally in a week or so, but will continue to practise weak side regularly so I am prepared the next time I do something dumb.
Never argue with an idiot. They will just drag you down to their level and then beat you with experience.--Red Green
