In my experience, a 1911 is just a little more likely to need attention/adjustment to make it run 100% than say a Glock. And that assumes one made by a good manufacturer, chambered for 45 ACP. They need lube. Other than that it's pretty easy. It's like my 45s don't know they're supposed to malfunction so they just keep shooting.
Now everyone, I am not the shooter CF is and I don't approach his round count. So don't take this as a dispute of what he posted. I respect your viewpoint CF.
