Need help determining causes this on a NEW 1911A

A friend of mine and I are trying to figure out what is cause a Factory New 1911A1 Rock Island Armory (Officer Type) to dent the casing about half way between the shell head and the front end of the hull. I know that these aren't really high end 1911 style pistols, but I wouldn't think this should be happening.
When fired, the pistol extracts and ejects every shell casing just fine but every casing has a pretty significant dent in the side of every shell casing in the same place.
First we tried another brand new recoil spring made for this pistol thinking the one in it might be too strong. That didn't seem to help.
We then thought it might be a failure of the ejector to strike the empty shell case soon enough to allow the empty case to fully clear the rear of the slides ejection port prior to leaving the slide resulting in the empty shell casing striking the rear edge of the slides ejection port opening.
Or, could it be that the extractor claws cut (angle cut on extractor claw) is a little off some how, possibly causing the shell casing not to extract at the proper angle so as to cleanly clear the slides ejection port opening, thus causing the shell casing to strike the rear part of the slides ejection port opening when the shell ejecting?
Any ideas or help related to what is causing this would be appreciated.

The extractor tension may also be an issue as Forge stated, it can bind the casing in place too long and become a reliablilty issue. But since it's working reliably and extracting cleanly it's probably only a royal pain if you reload your brass.
Use a stright edge that fits in the mag well and put it against the rear with the slide off and see where the ejector is to the edge.
It should be even or sticking out some with the same angle on the lower third of it.
