I have been trying to get info on converting a colt 1911 45 to a 9mm and just haven't been able to get any answers. I am wanting to drop back to the 9mm for cheaper ammo to practice with and stay with the 1911 style pistol. Haven't had very good luck finding a 1911 9mm to purchase without taking out a second mortgage so was considering changing one of my colts. Anybody got any ideas or info on how to make the conversion? 1eye
