I shot my first match with the new rules. I moved my holster slightly forward, and made major adjustments to my mag carriers. The match went very well, and after visualizing my mag changes in a very granular way on the first two stages, I forgot about it and had no problems.
I’m glad I have always run bullets forward because the hand trajectory parallel to the belt makes changes in mag carrier position less of a difference. With bullets out, I’ve always felt like very precise hand placement was required.
