Thanks for your comments! I've never had an issue like this before. I just spoke with the local gunsmith that the dealer brought the gun to initially to inpsect my gun. He only had the gun for about 15:00, and he said that he didn't remember exactly what might have caused it, but saw no issue wih the gun. He said it could have just been a freak thing. He did say that the primer was NOT struck, since the slide was not completely closed.
Ironically, his shop is less than 5:00 from my house, so if I have another issue, I'll just deal with him directly.
He said to just shoot it again and see what happens.
If the primer was not struck, it seems to me that the casing was on it's way into the chamber, and didn't make it all the way, and jammed. Why...seems to be the question.
Oh well, we're planning a trip to the range on the 17th, so we'll see what happens.
