For a true Commander length Barrel/slide/frame (4.25"), you have only a few choices
1. Colt
2. Paraordnance
3. Sig (slide is a little bit skinnier than most 1911's)
4. S&W (scandium frame)
5. Norinco
Kimber uses a 4" barrel lengthened to legal limits.
STI Ranger II uses a barrel that meets legal limits but it's not a true commander slide and the frame is a gov't frame, longer than commander frame so it won't fit in holsters made for Commanders
Wilson Combat pistols also do not make a true commander.
