Mine shoot well also.  I own several.
You will not find a more accurate 357, and you will find many that don't measure up in that department.  S&W copied the Dan Wesson barrel system (and a few other things) on their new 500 S&W.  It was a must to use the excellent DW technology if the big 500 was going to last.  Last I heard, they are planning to use the Dan Wesson barrel technology on ALL their revolvers eventually.  When that happens, S&W will begin to rival Dan Wesson for accuracy, but S&W does not allow for the user to interchange the barrels.  It must be done in the factory, although it a similar barrel and shroud system as the Dan Wesson.  I quess S&W would rather sell you 2 (or more) guns instead of allowing you to change barrels.  That is why I am glad Dan Wesson is going to keep making revolvers, even though they are also doing very well with the 1911's now.
