It is not the gun, but the clip that makes the difference, so news hounds will not have the clip capacity info until someone physically tries to see how many rounds will fit in the clip.(and that is not going to happen until later in the investigation)
Thanks for that. They had stated in the briefing how many rounds of ammo was still left in the box of 50 but I didn't catch the number. It would work out with the larger clips as they did say all the ammo from the shooting and what was left in the box would account for the one full box.
