Honestly, if you've never had a 1911 before, I would highly recommend Springfield Armory. They have some of the BEST customer service in the country. If you're looking for the complete package, I would recommend the
Range Officer. It's got everything you need. And you can find one new for ~$750.
If the adjustable rear sights aren't your thing, and need forward cocking serrations...then I would recommend their
Loaded model. On the street ~$825.
