You and me both...all mine have been 5".
Everytime I look at a commander size 1911 I wonder why I never bought one - especially those "bobtail" types.
I guess it's just that the full size ones I have run & shoot so damn well!
I love my Commander........it sees more action than my 5" 1911's.
I have several full-sized 1911 pistols, the one Commander, and a .380 Gov't (slightly larger than the Mustang .380). I would love to have an Officer's Model or Defender....along with a LW Commander.
Aw heck..... I'd take as many as I could get....alas, I do not have deep enough pockets.

A friend has a Rock Island Armory compact 1911 and raves about it.
