To OP’s original question, I spent the balance of 18 months testing 1911s in 9mm, and the results were interesting. These were all off the shelf models, usually priced around or under $1,000, since apparently my readers are fucking poors.
The best of the bunch was the Dan Wesson Commander in 9mm, and I regret having to send that gun back to Dan Wesson every single day.
The most surprising was a Rock Island Armory 9mm, that at final tally was over 5,000 rounds without a single failure of any type. That was a really good gun, and I used it as my main USPSA gun for a couple of years.
The worst was a Springfield Armory Range Officer which was just a hunk of garbage. It was worse than the Taurus PT1911 9mm that I tested.
