I thought 9mm rounds were well below that BC

Most lighter bullets are, but when you get into the heavy 147 grain bullets, they usually tend to hover around .17-.2 depending on the shape. The Hornady 147 gr XTP and 147 grain round nose claim .212, the boat tail (which is not typical of pistol rounds in general) likely helps the BC but even Sierra claims a G1 BC of .18 @ 1000fps and below, for their 125 grain FMJ. (They don't make 147's apparently)
Don't know what Magtech uses but they also claim a G1 BC of .201 for their 'Full Metal Jacket Flat'
