Sig would be my second choice. Much better choices overall would be a S&W 4014, 4013, 4513, or Shorty 40/45.
Any of these are better, more modern guns than a 1911 (although that's still one of my favorites after the 3rd gens and Sigs). And Glocks would be my last choice.
Much better polymer choices are the FNP/FNX's, HK's, and Walther PPS (in .40 S&W)
