colt defender/newagent are simply the best compact 1911 out there bar none.
i own a new agent it is 100% reliable feeds anything you stuff in it even empty cases. there arent many guns out there that will feed an empty case from the magazine. accuracy is superb. trigger is very good.
i have a SA Loaded Micro Compact 45 that is simply awesome. accurate, reliable and feeds evrthing i have put through it. lightweight and compact with a 3" barrel. downside is, most of the compact 1911's are pricier than there full sized brothers. MSRP on mine was $1370, and i got it for $1299 out the door. some people have asked if it's worth what i paid for it? to me, yes, every penny! it's a great little pistol.
