I was wondering if anyone else hasn't felt the need to upgrade their ejector (or any other parts for that matter) in their Gen 4 Glock 22. I have a early G22 Gen 4 with all the original parts minus the RSA which is the current version. I haven't had one issue with this pistol in the 5K plus rounds through it. There is the old saying of, "If it ain't broke, don't fix it." I tend to lean that way but I was wondering what others feel about it and what they have done. Thanks!
