1. Buy new with warranty... don't buy a used gun, it can be a headache someone else is getting rid of. Springfield Armory have an excellent warranty, excellent 1-800 support, if bad will fix fast, and pay the shipping both ways. Highly recommended ... they should have something at your price-point.
I disagree. My first gun was a used one and it was fine. Certain manufacturers, Smith and Wesson is one, don't care if you're the original owner and will take care of you regardless. I think I've had more issues with new pistols than ones I bought used.
