Either a Kimber 1911 Pro Carry 4" (compact) or a Springfield 1911 Micro Compact (sub-compact) depending on my mood. When I get the Springer set exactly how I want (sights, beaver tail, extended safety, refinishing) it will be my go to, but for now I go back and forth between the two. I carry them both in the same small of the back IWB holster, works well for either.
