I really love this SD40. Picked it up this morning. The slide to frame connection rattles like a can of marbles but an awesome gun nonetheless. Went to the range today, I had results that made me smile, and I'm a horrible shot with a pistol! Haven't been in the pistol game for long, and with my other (Bersa Thunder .380) I'm terrible! With the SD, I was making head and centermass shots (no groups to post pics and brag about though). I just need more practice and will get much better. The M&P Trijicon sights are awesome. Not a single FTF or FTE. The 180gr JHP's are great, and the recoil is easier than with the 165gr FMJ Blazers, but those have some screaming velocity on them.
