Police went with Glock due to marketing, price, and a similar trigger to a revolver. The price of a used revolver was more than the cost to make a Glock. Glock was able to give police departments brand new Glocks for their used revolver. While 1911's are more expensive, and require more changes in training.
Some police officers still carry 1911s. 362 police agencies that allow 1911 carry, http://forums.1911forum.com/showthread.php?t=268453
Yep and Glocks aren't cheap anymore. Which is why police departments are moving away from them. San Antonio is moving to S&W M&P 40sw for what they issue. State police here use Sig Sauer 226's.
