There are plenty of guns in your price range. You should be able to find a used G17 or 19 (if you consider the 19 full sized...) for around that. Just look around...ask your LGS.
I see some suggesting the SP2022. It's a good gun. My wife has one and so does her dad. But you have to be aware that it only comes with one magazine. In addition, I haven't been able to find mags for it less than $40 (and right now, I can't find any). So if you're like me and figure that minimum number of mags is three, you're looking at around $480...and that's assuming you can find any right now.
To compare, my Gen 4 G19 that came with 3 mags (and I've bought 2 extras) cost about the same as my wifes SP2022 that we bought 2 spares for.
