Sounds like the typical internet FUD.
I have had a bunch of 1911's in the past and still have over a dozen of them. All have worked reasonably well with the only real problems appearing in a couple that had bad recoil springs, a very easy fix. Heck even my 1914 vintage Springfield Armory 1911 that spent many years at the bottom of a lake is reliable.
Nowadays you can buy a semi custom 1911 over the counter that will have all the mods that you used to have to pay a pistol smith to do.
But.......... hands down, the most reliable .45 I have that will absolutely digest anything I put through it without any hiccups, is a HK USP .45
