Of those 2 choices, I'd opt for the SW1911 E series.
My SW1911Sc has been an outstanding pistol. S&W has invested heavily in equipment and resources to their SW1911 line. The Enhanced Models offer some revisions and features not found among the standard models (although the small 3" Pro-series has the oversize extractor).
S&W's customer service is a considerable advantage, I'd think, especially with pre-paid shipping both ways for the original owner for any warranty concerns.
While I definitely have no need
for a 10th .45 pistol, let alone a 6th 1911-style pistol, ordering an E series has been in the back of my mind since I heard about them being developed.
