Unless things have changed, I don't think Wilson makes a true commander (4.25"), but their Professional model is a 4". I have a CQB Compact which has a 4" barrel and an officers grip length, but mine has a cone barrel. I'm not sure they make the Pro with a bushing. Ed Brown, on the other hand, makes a true commander with a bushing, and I really like mine but can't necessarily see any advantage or disadvantage to either.
