Check the edition.
I THOUGHT yesterday's IDPA was to be under 2017 rules (The MD said he was not going to new rules until May), and so took my sawn off GM for use as a CCP-8, it's swan song as a competitive gun.
Nope, he changed his mind, 2022 book with CCP-10 and CoFs to suit. two rounds short put me into two standing reloads and twice left me with no makeup shots.
If I had known, I would probably have shot SSP-15. I will next time just for fun, then revert to ESP.
I did get good use out of the new Last Round Reload provision, though. That kind of popped eyes among those who had not read up, but soon they were doing it too.
