The Colt Delta Elite in Stainless Steel is the about the ultimate handgun built by Colt, in my opinion. It's got a Series 80 safety, stainless material, and a round that's not to be beat in many circles. If I had two, I'd install low-rise sights like Novaks, but mine is so perfect I'm afraid to mess w/it.
Keep the 10mm loads factory, Remington green box 180gr worked well for me, and install a buffer as a precaution. Enjoy, you're lucky, and many folks (like you've read) are going to be jealous that you have one.
