I don't claim to have tested all the pistols out there but I do have experience with the 1911a1. Quite a bit to be truthful.
I first qualified with one in 1966, didn't have any problems the first time. I carried one in SE Asia. I've crawled on my hands and knees in silt and mud (rice paddy mud is like clay) with a 1911a1 in my hand, sometimes I would give a flip of the wrist to shake off some of the excess mud, some times I wouldn't. It always worked.
I've carried one in the arctic where every thing froze up. Carrying them under your coat in a shoulder holster with the body heat, then as soon as it's exposed to the out side sub-zero temps, it would sweat and freeze AND FIRE. First round broke everything loose.
As to accuracy. I ran the AK NG Marksmanship Unit. Our Combat Teams were required to use "arms room guns" which means those old warn out, rattie 1911a1s. Some people couldn't shoot them, some could, (with training, all could). No matter how bad, a decent shooter could keep them in the 8 ring of a B27 style target at 50 yards.
I got mine in the mid 70's, made in 1942. I don't know how many rounds have been through it before I got it, but I've fired thousands of rounds of military hardball. Since I've retired and have to furnish my own ammo, its been cast RN bullets. It still works.
Granted, you have to concentrate on that little bitty front sight to hit anything. With my old eyes I have to use reading glasses. So I could keep shooting my 1911a1, I got the drug store glasses that allows me to focus on the front sight (instead of reading) and it works.
These old worn out guns will shoot if one only takes the time to learn to shoot them (pretty much the same for any gun).
