I have a Colt Combat Commander that I purchased in the middle 70 that I'm thinking about converting to 38 Super. Already have a couple of other 9mm which is why I'm looking at the conversion. My old manual which list parts has the barrel, ejector and magazine as the only different parts from the 9mm, everything else are the same. I see Bar-Sto sell barrels with bushings for the Commander and wonder if this is a good choice. Has anyone done this,
