The M1 Garand, when introduced in 1936, was MILES AND MILES ahead of ANY other military rifle in terms of accurate, rapid, fire under adverse conditions. It's still a VERY good rifle, for the following reasons:
1. It has among the BEST fully-adjustable mechanical sights EVER put on ANY rifle. (Yeah, some target rifles have more precise adjustments, but they are also very fragile compared to the M1.)
2. It has a very good two stage trigger, and it can be "tweaked" for better performance EASILY
3. It has VERY good balance for offhand shooting.
4. It is EXTREMELY robust. Even the weakest part of the M1 (the operating rod) still rarely fails in a way that renders the rifle unshootable.
Modern (post WWII) rifles are lighter, and hold more rounds, and recoil less, but fundamentally, are NO better in their ability to consistently put the bullets where the rifleman wants them. That makes the M1 pretty close to the pinnacle of rifle design and manufacture.
In case you cannot tell, I really enjoy the M1, and have 3 of them, one in .308. When I first got one from the old DCM, I thought it was an archaic novelty. Then I made the mistake of shooting it a bunch, and began to realize how really GOOD the M1 is in terms of "shootability". As I have said to others--if I can SEE it, I can HIT it with my M1. It's that "Shootable".
Besides, how can one not like the "rifle that saved the world"?
