I didn't quite answer the last questions from the OP.
What do I have (in a Commander)?
I have a O4691 Colt Commander .45ACP.
What do I like/dislike about it?
I didn't like the front sight becoming loose (tenon-type staked in) after 3,000 rounds. Along with that, I didn't like how I failed at being able to re-stake it four times where it didn't become loose again after ~100 rounds of shooting each time.
I didn't like sending it back to Colt for this with an estimated 1 month turnaround.
I didn't like the "rat tail" grip safety and replaced it with a Wilson Combat beavertail type. I didn't know I wouldn't like this grip safety until I shot the gun.
I didn't like no front strap checkering and put on 1" wide traction tape. I knew & planned for this prior to purchase and already had the traction tape which I'd used before on another 1911.
I didn't like the long trigger pad and replaced the trigger with a Wilson Combat flat trigger, which is medium in length. Again, I didn't know if I'd dislike the feel/reach until shooting the gun.
I didn't like the fit of the firing pin stop as the extractor was clocking, but had another one in my spare parts which fit better. There was only one of these models available and it wasn't as if I could choose from another with less clocking. Again, not a big deal.
I like the size. I like the feel when shooting it and its accuracy. Other personal-preference items I already had and changed were Kimber rubber grips instead of the cherry wood; and a McCormick "Power Mag", 8-round with basepad, instead of the stock welded-floorplate 7-round mags. While I'd rather have no firing pin safety, the Series 80 is not too difficult dealing with only four more parts.
OTHER.
While that Dan Wesson Commander-size without the bobtail looks great, the msrp on those are $1700/$2000 for SS/blue. My Colt was only $750 (msrp $800). If I were to do it again, I might try the Colt O4840XE alloy frame model with more of the items on it already which I ended up adding/changing on my O4691 model. I might even try a $4100 Wilson-Combat Elite Professional next time. It just depends on my mood on the day I buy a gun. With this Colt, I actually went in to buy a Glock G30SF (which I also bought).
Edited 3/23/16 to add: The Commander slide is already back and looks as if the new front sight willl stay tight for the rest of its life. I put 200 rounds through it today and its doing fine.
