Favorite alloy-frame 1911 caliber out of these?

Love my LW Operator - feels a pound lighter than my Loaded with a 10rd. mag in it.

Yea, it's a big difference. A 46 ounce loaded steel 1911 is just too much.

The rimless brass is dimensionally 9mm case head.
It’s common to have both types of brass cycle fine with extractor “tuned” for Semi rimmed Super brass.
(Most production 1911 have Zero “fitting” of extractors to begin with, which is responsible for a lot of indictments of “unreliability”)
Pretty simple to adjust tension if it doesn’t.
An external extractor which functions from a coil spring should work fine.

What about extraction / ejection with the super comp?

Does it require an adjusted extractor? What if a gun has an external extractor?

I have reloaded super comp by accident with zero issues. Feeding, firing and extraction all good. But, the .38 SA press shell plate doesn't like it. Without the rim they sometimes get pulled out by the re-sizer dye. When I find them I put them in another box and when I get enough I'll switch over to the 9mm shell plate and load them too.

^ This.

It’s been a few years, but I think I used a .223 shell plate with the Super Comp brass.

Yeah, that should work too. I remember reading [American Rifleman?] that the basis for the 9 x 23 Win round was shortened .223 brass.

Correct.
The major difference between the SC and 9X23; the SC is a straight wall case, the 9X23 a taper case and arguably thicker case wall- depending on Brass manufacturer of the two.
