Congrats on the new gun. When the dealers have trouble locating the gun you want, that's when you know you've got good taste. I don't think I've ever been able to walk into a shop and find the exact gun I wanted to buy.
You'll enjoy the 10mm. I shoot a DW and my FIL has a Colt Delta Gold Cup which are fairly rare. 10mm is a beast! Post some pictures when you can.
