Congratulations on your first fire-breathin' plastic hand cannon, Sucklead! Sounds like it's been a long time coming for you. Smart move on picking a model that has the rail system.
I had a glock 31 (.45 caliber) and loved it...until I picked up an XD for the first time last year. I now have two XD's in its' place, one in 9mm and one in .45. They both put together some nice groups and are more comfortable to shoot than the Glock. I paid the same for each of the XD's as I did the Glock, but they came with a holster, two mags, a mag holder, lock, speed loader and cleaning brush. You can also opt for the light attachment instead. I went ahead and bought the lights as well, plus tritium sights.

My Glock came with an extra mag, a case, and a sticker. LOL.
