Go to a range and shoot a few guns before you buy one. Shoot a revolver, shoot a 1911, shoot a Desert Eagle, (most ranges around here rent them because people want to try them) shoot a .22, 9mm, .40, .45 etc.
In my opinion Springfield Armory is the BEST* route for a 1911 because of the customer service and warranty.
*=unless you have some knowledge/aptitude in mechanics of firearms, then the best 1911 ever is a series 70 colt. The series 80 has some bs safety in it and proprietary parts.
Taurus is hit or miss, you might get a good one or you might get a lemon. Customer service is in Florida, while they are made in Brazil by Taurus.
S.A. is also made in Brazil by a very reputable* firearms manufacturer, then sold out of good old ILLINOIS.
Really though don't get a desert eagle.
*= IMBEL, they also make the best FALs in the world next to Belgium made ones.
