I suppose everyone is aware already, but S&W is introducing a new series within the 1911 family to be known as the E Series, which I am told stands for "Enhanced."

There will be 5 inch full size in glass bead stainless, 5 inch full size with Picatinny Rail in both glass bead stainless and melonite finished stainless and Commander length models with the Ed Brown Bobtail mainspring housing. There may be others, but those are the ones that come to mind.

The will have different extractors, different grasping serrations on the slide, different grips, serrations of some type on the tops of the slides to reduce glare, titanium firing pins and an enhanced ejection port.

I am sure more information will be released soon, but the SKU numbers I know about are:

108483 45 ESER 4.25 MEL
108485 45 ESER 4.25 SC 2TN
108482 45 ESER 5 8R SS
108495 45 ESER 5 CT 8R SS
108409 45 ESER 5 RAIL MEL
108411 45 ESER 5 RAIL 2TN

The descriptions are sort of vague, and I do not know any more details other than the rather cryptic descriptions above. I do know that SC means scandium and that CT means Crimson Trace. MEL means melonite.
