Hey there!
Well, I saw your second post, and I have more time now, so I thought I'd say a few things.
First, for $390, I doubt that you could get a new gun with night sights (at least one worth buying). However, I have an EAA Witness in 10mm that I just love. I had some problems with it initially, but soon found out that an old, defective magazine follower wazs to blame. An e-mail to EAA had a new follower sent to me free of charge. No problems since.
You stated in your second thread that you wanted SA or DA/SA, and palm swell if 1911 design. I REALLY think that you should try the Witness, or as another person suggested the CZ line. The reason for this is that you can choose to carry the gun either DA first shot or in SA "Cocked and Locked". Personally, I have never used the double action trigger of my Witness--I always use it single action because the trigger reach is a bit long for my stubby little hands. Speaking of hands, the grip is one of hte most ergonomic that I've ever felt, and I've felt a whole bunch.
If your looking for a .45, another option to look at would be the Ruger P-97. Reliable and accurate and not very expensive.--Night sights should also be attainable.
Good luck
