I have two Colt Government model 1911's in 9mm. One is blued, the other is stainless. They both have the same issue. Using 115 grain brass ammo of different brands, it ejects casings up and rearward, almost in an arc above the right side of your head. It will hit you in the forehead with brass sometimes. I had a casing land in between the bill of my hat and glasses and sit there on my eyebrow. Aluminum casings will get flung farther to the right and away from me. The only other 1911 I had was a Charles Daly .45 a few years back without this problem. Is this a 9mm 1911 thing, a Colt thing, a Colt 9mm thing or a combination of all? Can a gunsmith change the extractor spring? I'm not working on a 1911 myself. I don't have the time or patience.
Thanks in advance for pointing me in the right direction.
