I borrowed a CMP Garand for a month to see if I liked it enough to get one. I didn't, at all.
As battle implement it was one war too late. By 1944 other armies already transitioned to widespread issue of assault rifles and submachine guns.
The Korean War, ouch. From Wikipedia on the PPSh-41.
"Though relatively inaccurate, the Chinese PPSh has a high rate of fire and was well-suited to the close-range firefights that typically occurred in that conflict, especially at night.[29] United Nations forces in defensive outposts or on patrol often had trouble returning a sufficient volume of fire when attacked by companies of infantry armed with the PPSh. Some U.S. infantry officers ranked the PPSh as the best combat weapon of the war: while lacking the accuracy of the U.S. M1 Garand and M1 carbine, it provided more firepower at short distances.[29] As infantry Captain (later General) Hal Moore, stated: "on full automatic it sprayed a lot of bullets and most of the killing in Korea was done at very close ranges and it was done quickly – a matter of who responded faster. In situations like that it outclassed and outgunned what we had. A close-in patrol fight was over very quickly and usually we lost because of it."[29]
