Sounds like you might be out of a revolver sooner than you've planned ! Might be time to start playing seriously with a .22 LR for left-hand practice, to build hand strength. Question, what "eye-dominant" are you ? I'm right handed but left-eyed ! Makes for fun at times, what I did while shooting competition was in our bullseye league, I'd shoot 1 week RH, the next week LH, just for the practice for "weak-hand" stages. I got to the point that I was shooting about 285-290 steady, either hand. I was using a 1911 for both "any centerfire" and .45 parts of it, and a Ruger MK I for .22 RF. Have 2 grips for the Ruger, both by Volquartson, a RH & a LH full target grip. They fit my hands so well, after I first grip the pistol, I really don't have to forcefully hold it, just more or less point it. Had to change them between weeks, as a RH target grip don't do worth SQUAT in your LH !
