45 ACP 185 SWC adventure

Interesting, the middle one has feed lips that to me release too late to be WC but has the parallel lips. The one on the right has the early release I attribute to WC style.

You certainly have more knowledge about the 1911 than I do though.

Here is where I go when I can't remember something about 1911 mags.

Great information at these two links. Thanks.

Here's a quote taken from the first link: "The Colt hybrid mag was everything its reputation made it out to be. Its tapered feed lips didn't alter the fundamental feeding mechanism, but let the cartridge rise up in the process. By smoothing out the extreme motions seen in wadcutter mags, the hybrid magazines provide a little more leeway for variations in bullet shape and gun dimensions. Chambering felt smoother and slicker, as well."

This would explain why in my testing the hybrid feed lips proved to be the best of the bunch.
