Accuracy? I'm told of poor bullet headspacing?<HR></BLOCKQUOTE>

Colt initially tried to use the case rim to headspace the cartridge in the barrel. Due to production tolerances, and the lack of a true rim like a revolver, the headspacing tended to vary quite a bit. In 1988 Colt changed the headspacing to the case mouth so accuracy then was on par with the other cartridges. If you're looking at used Supers I suppose it would be good to know its production era although you could always re-barrel if one of the earlier ones struck your fancy.

Colt dropped it later and has not re-introduced it so it appears to be a wash. I understand that most enthusiasts changed them out for solid bushings fearing breakage of the fingers. Doesn't appear to have been a big issue either way so if you find one you like with it I wouldn't worry about it too much.

Better to go post war? Pre-war? GI?

As has been pointed out, for the most part the idea of better production periods doesn't work too well. You could have an old one that's a piece of junk and a new one that is a knockout, and vice versa. Far better to judge each one on its individual merits.

What have they got these days, current? Series '80's, I see ... what's that? 1911AI and 1911's, GI spec, new? What the hey? Over?

Series 70= No firing pin interlock
Series 80= Firing pin interlock

The Series 80's are not usually appreciated as most feel that the have excessive trigger creep due to the interlock. This isn't much of an issue with production guns as the firing pin spring is quite stout and IIRC it takes something like a 20ft drop straight on the muzzle to get a discharge from firing pin inertia.

Race guns OTOH could theoretically have an issue as frequently main spring pressure is cut to improve trigger feel and cycling with light competition loads. This can lead to light primer strikes with production firing pin springs so the FP spring pressure is cut too. Of course due to the trigger feel issue the Series 80 isn't preferred for competition so this is another item that appears to be a wash.

The most obvious difference between the 1911 and the A1 is the finger cut outs in the frame just behind the trigger. there are a couple other items but thats the big one in my eyes. Look at the pics of the WWI repro on Colt's site and compare to the 1911's and you'll see the difference.
