To use the 92 as a major, you need to change it out to a 96 (CDNN has the kits).
Bottom line is there used to be a time when you could use/load 9 to MPF and run the class, but due to more than a few pistols coming apart from the hot loads, they now have gone to the 40 as the smallest cal to be a MPF. The really funny part of all this was the old MPF used to be 175 in USPSA (when guys where blowing up pistols), and now with it lowered to 165, it way easier to load MPF safely in the 9 platform.
As for running the 92 in limited, I can say with great conviction, it's totally the wrong pistol for that class. The DA trigger pull first pull, compounded by the long SA pull does not lead to consistent fast runs. For a mag round count, my double wide 40 mags top off with 19 rounds, and as stated, every shot that is out of the A zone is losing you points compared to someone shooting the same target zones, but using a MPF.
To keep is simple, if you are going to run the 92, keep the pistol in the production class where it belongs.
P.S. Just so you know, I do own a 92, and have used the pistol for the production class.
