I have heard stories about the iconic M1 Garand clip ejection ring. One being that soldiers eventually started to throw empty clips on the ground and would wait for the enemy to pop their heads up and then shoot them like they were turkeys.
The Russians also had the semi-auto Tokarev SVT-40 at the start of the war which the Germans didn't copy until a few years in with the Gewehr 43. The Japanese and Italians may have had their own too.
