About the Stgwhr 44, if it was so good, why no country used it?

Err, silly question. Some are still in use today in third world countries, but not many were produced in the first place.
Not one piece of German WW2 equipment was produced after the war but quite a bit was used, Panzer IV and V were used in some countries and their 75mm guns continued to be useful for a while. The "problem" was that Germany was neither supposed nor allowed to build weapons anymore. That doesn't mean the AK-47 was bad, but there were definitely political reasons why the StG-44 wasn't used by any army after the war, there were probably not nearly enough to equip an entire army and have replacement parts left anyway.
