In general, I agree. But I do think this author is glossing over the reliability thing a bit. I've certainly owned quality 1911s from reputable manufacturers, with no aftermarket parts in them, and using quality ammo, and still experienced issues at times. To deny that 1911s can be finicky is suspect, to put it kindly.
Sometimes they need a bit of a break-in period, sometimes they don't. Some will feed everything, and with some, you need to find the right ammo/mag combo for that particular gun to ensure reliability. And it doesn't always have to do with how much you spend, either. I've seen $800 1911s that ran more reliably than $3k 1911s. Denying this is just willful ignorance or blind bias, imo.
I do agree with the author, however, that 1911s do not take great skill to maintain, assuming you have a minimal amount of mechanical aptitude. They aren't particularly complex, and regardless of what platform you dedicate yourself to, you should get to know it, inside and out.
That said, I love shooting 1911s. And when you have one that is reliable, whether it was that way straight out of the box, or whether it required a little tweaking and love to get it there, they still, to this day, have no rival.
