Thanks for all the comments. I went ahead and dragged my tail to the plate match anyway and shot rimfire/iron sight class. No BOOM, no holster, didn't have to save brass, etc. It's about the least stressful shooting I could think of. But then, my gun malfunctioned on 4 out of 5 stages. Oh well, I was outside with good people instead of home alone, anyway.
The pain subsided about halfway through the match and I feel better now, just tired.
