The requirements for a second reload were not mandated. Stage called for 18 rounds. Only ESR & SSR (REV) shooters had to make a second reload at P1, as per the standard rules.
Everythings else aside, the question/issue is: by an exact letter/word reading of 3.4.1 and 3.4.2, where a reload with retention has been mandated in the COF, if the shooter runs the gun dry to slide lock but retains the magazine when reloading, is that an 'emergency reload' or does it satisfy the requirements for a 'reload with retention'?
The arguement given and held by the MD that, as per 3.4.2, a reload with retention requires the gun to be partially loaded (round in chamber) as well as the magazine being retained. Since the gun was shot empty to slide lock, there was no round in the chamber and therefor, even though the empty magazine was retained, it was an 'emergency reload' not the mandated 'reload with retention'.
