For targets and HD, you don't mention concealed carry, I think the Glock 30 is a bit on the small side. It will work though. I'd explore larger frame sizes. Glock 21 for instance. You might do well to consider the Springfield XD series as well, they are comparable in price & style. Check Out the Stoeger Cougar as well, they are old school metal frame Beretta's manufactured in Turkey, well made and very good value. There are a number of good guns that can be found in your price range. If possible, go to a range and rent several different models and see which you prefer.
I also recommend that you seek some sort of handgun familiarization training if you're a complete handgun novice. This may also help you in you search.
