The new RO Champion 9mm looks like a lot of gun for the money ($753 on Bud's site). I wouldn't worry about the configuration, Springfield worked any bugs out of their aluminum framed, bull barreled 1911s long ago. My LW Ultra Compact 9mm is about 12 years old and even with it's 3.5" barrel it runs like a champ and is a very comfortable gun to shoot.
If I didn't already own some Commanders the new RO Champion would definitely be on my radar.
