I think it's also worth mentioning the Colt Defender series.
Colt O700D Defender 3" is one of the few 3-inch 1911's I've seen work reliably.
A big plus for me is that the Hogue grips seem to automatically align the sights when presenting the gun.
Also available in 9mm.
If you want the blued version, the Colt 7810 Defender New Agent .45 is your model.
The New Agent series features trench-style sights to minimize size.
Also available in 9mm.
The Colt 07812DA Defender New Agent DA offers a DAO trigger. Also available in 9mm.
Colt even has a full sized "Government" model that is DAO
and uses an aluminum alloy frame.
A lightweight DAO "Government" model. The 1991DA.
MSRP on these guns is about $1,000 ... ± $20 or between about $850 to $900 sticker price.
