The Garand is a marvelous rifle, powerful, well made, and hard hitting. GI’s in WW2 had the advantage way over any bolt action rifle the Axis used.
The Mauser was a good rifle but again, working that bolt in
a fire fight could be a serious liability. And the Japanese Arisaka. Good Lord you couldn’t have design a worse battle rifle if you tried.
Now the MG 42. There was a weapon. Man, that thing was fearsome. Still in use today. Incredible rate of fire.
The Germans mounted the firing pin for the MG 42 on a small tray type assembly, about 2x4 inches and in each of the four corners of this ‘’tray’’ they put roller bearings so the whole firing pin/tray assembly moves back and forth very rapidly.
What happened to all those garlands that Korea wa to return? Lend lease.
Have you ever seen an FG-42? The Allies were fortunate that the Germans didn't hit on that design in the interwar period and make it their primary battle rifle.
