From my experience - for what it's worth - all 5" 1911's are the same with regards to holsters - excluding tactical rails, which don't belong on 1911's in first place
Where things can be a bit challenging is in the smaller sizes. Depending upon the manufacturer, I've seen the mid size/commander size at 4" or 4.25" inches. Compact/Officer sizes at 3 or 3.5".
With that, the holsters will usually fit - just not perfectly. I've had people tell me that they've successfully used a Commander size holster for full sized guns - the nose just sticks out a bit.
Given all that - my professional opinion is that each of your guns should have it's own holster. Usually in several different colors and styles. Maybe two or three holsters per gun just to be safe.
