It is a peasant's weapon with poor accuracy good only for close in fighting. Ask the AK-47 armed Iraqis who charged the soldier of the 507th who died after killing numerous Iraqis at 200 yards.
"It is a peasant's weapon with poor accuracy good only for close in fighting" which is what it was designed for as first the Germans then everyone else realised that 200yd+ accuracy was of less importance in a mobile war like that at the end of WW2. It's a great example of the "KISS" principle as well.
