You should be able to use the same bushing unless one of the barrels is very worn or different spec. (e.g., a fit barrel) than the other. This is likely possible but you won't know until you try.

The ejector, slide stop, etc. are the same for those two so no need to change anything else but the magazines. As to where to buy, I can't tell you everywhere buy makers include Kart, Colt, BarSto, Clark, Schuemann, etc. A look in a Brownell's catalog could probably help you.

You might have to replace or alter the extractor. I have had one gun work in both calibers with the same extractor, the other not.

If the 9mm barrel is not factory, it seems likely that someone converted that gun from .38 Super to 9mm just by replacing the barrel, usually a feasible conversion. The conversion back should present no problems. If the gun was originally made in 9mm, there might be some problems in converting it to .38 Super, mainly in the feed ramp and the breech face.

9MM

I have seen colts that came from the factory in 9mm(they take a special mag) and I've owned a colt goverment model in 38 super. I should have had my asskicked for selling it.
The 9mm mag has a little deal added to the back of the mag to allow the mag to shoot the 9mm.
