I think people buy a 1911 like a Kimber or Dan Wesson, don't bother to clean/lubricate it and go to the range and have issues. I've got a 3" Ultra Carry 9mm Kimber that was traded in at a great loss because it's first owner never bothered to read the manual, follow instructions.
I've had it for three years and it has never jammed on me with simple cleaning/oiling.
I've always been afraid of 1911 platforms under 4". I know they can be made to run like a Swiss watch but everything in set-up is just much less margin for error. May be an unfounded bias from some of the early Officer's Models teething problems. Funny, I had a Star PD .45 at the time that did run like a Swiss Watch.
