Regarding quoting some "unacknowledged source", this historical data is so commonly known, it doesn't need an acknowledgement - if you need some I guess I could spend a 3 seconds on Google and get some for you.Am I misunderstanding this or are you quoting some unacknowedged source?
The AK47 never saw combat in WW2 and was only adopted by the Soviets in the very late '40's.
How could the Germans have developed the STG44 to use a "AK47 vs STG44 intermediate round"?
Irrespective of the pedigree, timelines the StG44 is the granddad of all "assault rilfes".
Is it the most significant firearm ever produced?
The question needs clarification.
Could be a generic type of weapon (as above, the "Assault Rifle"...or the Gatling Gun, the Maxim come to mind, as do the Mauser bolt action rifle or Enfield SMLE blah! blah!) or
Could be a weapon that literally changed the course history...Gavrillo Princip's Browning for example, or the guns that shot Lincoln or Kennedy, Adolf's Walther that he used to blow his brains out......
The Germans produced the StG44 to fire the 7.92 x 33 Kurtz round ( a round still in use today around the world), very similar to the 7.62x39 AK round-prior to the Soviet effort.
