You only need to swap the Ejector on a G23 frame if you are adding a G19 Slide.
If you go the conversion barrel route, the barrel is offset slightly to accomodate the different ejector configuration. In my experiences running a Lone Wolf (40-9) barrel in a G23, I had 100% reliability.
What you need to convert a G23 to shoot 9mm:
- 9mm Magazines for ultimate reliability
- A conversion Barrel (Lone Wolf, KKM, Storm lake) all are good.
