I have developed severe osteoarthritis in the wrist of my dominant hand (left). My primary shooting interest is self-defense and my longtime carry gun has been a Glock 19. I probably will have to switch hands but before I go re-buy holsters or other things I wonder if anyone has any ideas about how it might be possible to keep using my left hand. Wrist braces? Different pistol (preferably a reliable caliber & not a peashooter)? Something I haven't thought of?
