Laying aside the USGI option for now (I will have one some day, but what applies to those doesn't really apply to a commercial gun), the budget is around $1000. It wouldn't have to be a carry gun, as I'm quite happy carrying that big ol' Springer. Don't really want a safe queen. Something I can shoot, something I wouldn't mind carrying (which is pretty much any 1911, really), something different from what I have now.
LGS had a Delta Elite but it's gone. The Talo LWT Commander in .38 Super looks pretty cool but they're pretty proud of those.
I guess I should go through what I like and don't like in a 1911.
Size: no smaller than four inches, no larger than five.
Caliber: any.
Sights: any.
Trigger: not a huge fan of the three-hole triggers but they're okay.
MSH: prefer arched but flat is okay.
Thumb safety: ambidextrous is useless to me and I don't particularly like the appearance. I prefer the traditional short, wide type to the long, skinny ones.
Grip safety: I really like the A1 style. I don't have very large hands and I find that the ducktail and beavertail safeties make it harder for me to manipulate the controls. I grip my 1911 high and have yet to suffer hammer bite, so the extended grip safeties don't help me any.
Hammer: prefer spur or circular (Commander style) hammers. Not much on skeletonized type.
Fire controls: doesn't much matter. I have no particular opinion on Series 80 vs Series 70 or earlier. I even put up with my Springer's ILS.
Materials: any.
Finish: nothing too shiny.
Serrations: depends on the gun and how the integrated whole looks.
Geez, maybe I ought to just build my own!
