Both Springfield and Kimber make a very good gun. I'm sure somebody gets a "lemon" now and then, but chances are you will be happy with either. Since this is your first gun, I wanted to make sure that you knew there are some fine 1911 makers out there that you did not mention. Smith & Wesson, Charles Daly, and Dan Wesson are three other brands I would look at. I was impressed with the quality of the last Dan Wesson I looked at, Charles Daly is hard to beat in price, and S&W is always a good choice IMHO.
There is in life perhaps one fleeting moment when the courage, dedication and resolve of one man gambling against all odds will alter the destiny of nations.
