I have a problem with a Kimber Pro Carry II ejecting spent brass back in the shooters face. The gun was purchased new several years ago and has always had this problem. Initially it sent about 33% on spent brass back in the shooters face. It is an internal-extractor model like a standard 1911. It has about 500-1000 rounds through it. The recoil spring is original and feels to have almost the same pressure as my other pro carry that has brand new Wolf springs in it. The problem is experienced by all shooters who have shot the pistol, regardless of eye or hand dominance. Limp-wristing has been ruled out. Multiple brands of 230 grain hard ball have been tried, as well as light 200 grain LSWC target loads (.45ACP). I have owned five other 1911 style pistols and have never had this problem.
Below are details about my previous attempts to resolve the issue:
-Checked extractor for clocking. Extractor was firmly held in place and was not clocking.
-Installed a Wilson Performace extractor. I tuned it as instructed by various websites and installed it in the pistol. - No change in symptoms.
-Added a recoil buffer – No change.
-I took the original extractor and stoned the bottom of the extractor claw to further round it as described here: http://www.brazoscustom.com/magart/0609.htm. I also increased the extractor tension on the cartridge. I installed the tweaked Kimber extractor and fired 4 rounds of 230 grn ball and 4 rounds of mild 200 grn LSWC loads. All 8 spent casings were directed into my face.
I initially did not notice any obvious dings or other abnormalities to the spent brass. However, on closer inspection, I just noticed that the spent cases fired today all have a tiny ding on the side of the case approximately 3/10” from the base of the case. I think that this is a result of the severe rearward ejection, but I’m not positive.
Does anyone have any suggestions of what I can try before I start stoning and/or replacing the ejector, or am I correct that this is the ejector is the next area that I need to focus on to resolve this problem?
Thanks,

ETA- I just noticed a couple of faint brass markings on the ejection port between the 1:00 and 2:30 positions.
