The early ones were actually pretty tight, and the WW2-era pistols were quite good when they were new.
I was a unit armorer when I was in the Army in Germany in the late 80's/early 90's. We had those SAME WWII-era pistols in our racks. They'd been rode hard and put up wet in the intervening 40-odd years. None of them were accurate any longer.
Our brigade armorer (the guy who was actually an armorer vs advanced maintenance man like me) told me the Army hadn't bought a new 1911 since WWII. We had one or two that shot straight, but only after they'd been determined to be so bad that they needed to go to depot for repairs. Came back much tighter than they left.
A group of us used to shoot our personal weapons at the range on weekends. I fired nearly every privately owned handgun in the company. Every single one of those was far more accurate than the issued 1911s. My personal 1911 was so loose I could barely qualify with it, yet I was a good enough shot then to dump entire magazines from mine or my friends' personal weapons into the head of a military silhouette from the 25 yard line.
So, there's some basis to the complaints on aged and poorly-maintained 1911s. I suspect that the complaints started long before the 1911 inventory aged to the point that they were merited though.
On the main topic: I'll take reliability. At the range most encounters take place, even my poor, abused, issued 1911 would be accurate enough to get the job done.
