Don't get me wrong, I'm a big fan of S&W 1911's. The fish scale serrations are a very practical and effective surface for racking the slide but, they're a major departure from traditional. That said, I've come very close to buying an E Series that's gotten the S&W Performance Center treatment. I'm sure they would grow on me eventually!
I can't recommend this E series enough. I looked at the performance series one but the price tag was a bit to much for me, and I don't like compensated barrels. As accurate as this one is plus how crisp trigger is I'm not sure what more they could do.
