I like the Marines having the choice. My personal choice is the 1911. I took the 4 day combat handgun course at Front Sight. My Colt M1991A1 was the only weapon to go all four days without a malfunction. I sent over 800 rounds downrange that week. 15,000 rounds later, the weapon still puts lead on target.
I have a Springfield Armory 1911A1 Government Model. It has about the same number of rounds through it with the same reliability. It has never malfunctioned. I have always taken care of it and it is just nice and broken in.
