"It's a real shame that Kimber is the only manufacturer to make a compact 1911 with a 4" barrel like this anymore."
Not so. No need to appeal to a MIM-parts Kimber! Don't forget the several editions (blued, stainless, lightweight) of the Les Baer Stinger.
It has a 4 1/4" barrel, same as the Commander, and an Officer's Model sized frame, which aids concealment due to the shorter butt.
I carry mine daily.
The configuration is the same as the original Colt CCO, and I consider it an optimal 1911 format for CCW.
