I have an STX and it is a wonderful shooter. As an admitted Sig fan, the slightly more square slide profile is not a problem to me. Mine is accurate and has shot cheap hardball, re-man moly coated semi-wadcutters, anything I've thrown in it.

The two tone finish and burl grips make a pleasant combination to my eye, but I've sometime put a nice pair of walnut grips on it.

For full disclosure I also have the Sig Target 1911 with the rather strange wooden mag-well grips and a C3 compact in .45acp. The STX gets slightly more range time.
