I read a book one time ( I wish I could have kept it but it belonged to someone else and the edition was out of print) that was written just prior to WWII and there was much discussion about "if the new-fangled Garand semi-auto would hold up as well as the venerable 1903 in service". The author seemed to indicate that the Marines, in particular, were loathe to give up their '03's for the "new" gun.
I guess WWII settled the question . . . . .
Surprisingly, it did not. Military History magazine had an article on the subject once. Some diehard old Marines didn't like the M1 Garand right up through Korea, complaining that it would freeze up and just become a single shot anyway.
Plenty of people didn't like the M1 during WW2 and not just die hard bolt action fans, taking an M1 carbine or SMG of various types in preference if at all possible. Of course the real hot ticket for the "operators" of the day was a captured Stg 44 in the ETO.
In the Pacific, you were the "cool guy" if you laid your hands on a Thompson or even an M3 Grease gun.
The happy switch was a popular accessory in WW2, to the point that people were field modifying M1 carbines for full auto fire. (See Richard Matheson's autobiographical novel of late war infantry combat in the ETO.)
High capacity weapons were also sought after by some Marines who'd modify their Springfields to take BAR mags. This seems to be a forgotten/lost modification but shows up in some period accounts and war time combat paintings. I belive that there is also a passing reference to it in "The Thin Red Line" (the novel, not the movie) which was written by an Army veteran who served on Guadalcanal.
By 1945 it was hoped to replace the M1 Garands with a selective fire weapon taking 20rd box mags that could interchange with the BAR for the invasion of Japan. When the invasion never happened, and budgets were slashed, the Garands lasted longer, not being phased out of some National Guard units until the early 80s. Contemporary accounts of the Army from that phase viewed the National Guard poorly with references to "the National Guard and their old M1 rifles". See "At War with the Dragons" about a series of field training excercises circa '81 or '82 against the mock Soviets at that national training center for reference and an interesting view of the Army in the early Reagan years in general.
It's interesting to see the types of people that are into different types of guns. When I go to the range, there are lots of young, inexperienced shooters burning up 223 round in their black rifle....on the other end, the older guys with their M1As and Garands are more laid back, more learned about their guns, and a hell of a lot more fun to hang with...
Bah. New fangled repeating rifles and smokeless powder. Who needs 'em. Lazy kids today. First with their fancy show off percussion caps, then around '60 or so, showing up with those Henry repeating rifles and tearing the ranges all up. Sharps carbine was bad enough, then they had to go and get repeaters.
