I'm now wondering if the factory servos on the 4400M are actually geared differently than the steppers on the older 4400C.

If I look at DC servos commonly available and in the same weight range as the AC units from Mitsubishi, they are around 600 and 1100 oz.in. respectively. Geared 5:1, they would be roughly the same power as the AC servos on the 4400M....
