Might want to talk about the composition of a US Army versus German infantry squad and the firepower of 10 M1icon Garands versus X K98kicon's. Of course you are taking the BAR and MG42 out of the equation but the point being that the supressive firepower of 10 M1s versus the K98 when the MG is reloading or displacing or after it being knocked out is not trivial. IIRC a trained rifleman can get off 3 clips of aimed M1 fire in the same time it takes to get 2 5-round clips of M1903 fire. And the M1903 is very similar to the K98.

Of course check other sources to make sure I got that right. There was a Mail Call with Lee Ermy on the Garand versus M1903 not all that long ago. Maybe you can find it online somewhere.

Another point is that there were ~4 million M1 Garands produced by the end of WW2 but only 400,000 G43s. Granted the G43 started later and was never the standard infantry rifle, but the Garand was the standard US infantry rifle and that was enabled/supported by industrial output.
