The XD [b] [red]IS[/b] [/red] the HS2000 with the added make-up that Springfield Armory put on which raised the price up by around $130.00
I have a 3rd Gen 9mm HS2000 and I will swear to its accuracy. Has all the neat features of the 1911, Glock and Walther all rolled into one gun.
But the best thing about it is the availability of hi-caps. The hi-cap for the Beretta 92FS and the S&W 5906 will work with a little modification.
Having seen pics of a Glock Kabooooommm where the chamber was basically torn apart, I compared the thickness of the side walls of the chamber with a Glock 22 and it is just a hair thicker. With this observation, I am quite hesitant to get one in .40 S&W.
The only thing that I don't like about the HS2000 is the trigger slap. After a few hundred rnds, you will start to feel it on your trigger finger
YMMV
