I’m sorry but there really isn’t a good gun in that price range, unless you’re considering a used Revolver.
There are more break ins for weapons in vehicles, these days. I don’t really recommend that, either.
I’d recommend a 9mm. Ammo is $160-$200 for 1000 rounds. Larger calibers run much higher.
If you look, you may find a used compact or full sized Glock around $400. With that said, you need to invest time and money on training, holster, spare magazines, a safe or lockbox, and ammunition. Range time is also costly.
I see the true expenditure of gun ownership to be at least $1000.
Just consider what your life, peace of mind and safety are worth.
