Let me clarify:
A 1911 can be tuned to be more reliable that most other pistols due to its simplicity.
I would not run any pistol directly out of the box. Cleaning and inspection first is essential.
I would trust a new military 1911 to be reliable new, as reliable as any modern handgun.
If a Glock were taken to the tight tolerances of many custom 1911 pistols, or was made by a wide variety of manufacturers like the 1911, I would expect a high number of malfunctions.
My background is similar to yours, but inverse: I came to the 1911 after being dissatisfied by more modern designs, including Glocks.
Certainly to offense meant.
