I can't speak for the G30 but had a 19 as my first carry gun. I loved it. Carried well and was nice to shoot. I now carry a 26 and couldn't be happier. I personally like 9mm over a 45. Less recoil and cheaper to get. But like others have said, it's a personal preference. Glad you got what you wanted. I don't think you can go wrong with either.
