Photos...This is as much as you might need to remove, as this gun functions 100%. I remember doing something to this ejectory maybe 3 years ago, don't have an untouched one to compare it to.
I took a picture of the breech face while I had the gun broken down. See how the firing pin hole fills with powder residue. Also see the gunk under the extractor and filling in the recess for the rim of the bullet. This needs to be cleaned with a pick every 500 rounds or so and the firing pin removed and the gunk in the hole pushed out of the firing pin channel from the hammer end.
But no, I did not clean it this morning. Not necessary quite yet.
Failure to eject is also affected by the slide velocity which is affected by lubricant choice and the hammer spring as well as the recoil spring. I use slide glide light in the summer, but I have to add some oil when the temps get down to 40-50 degrees F or below. I use only oil most of the winter and a 17# hammer spring year round. I don't replace the recoil spring very often at all. Only when the gun starts failing to go in to battery completely when the ramp has a little grunge on it.
So, after you make a little modification to the ejector, try some light oil like Rem Oil on the slide rails and see if that doesn't help some too. If the 22 casings are falling at your feet, you have a slide velocity problem. Mine land 5-10 feet away at about 4 o'clock with the ejector shape shown above if the target is at 12.
