I've owned some Colt Commanders. I've found them always to be ultra reliable, but way lacking in the accuracy department. They are quite well suited for defending yourself at all reasonalbe distances, but a target gun they ain't. I wish I had one now.
You know what? The most accurate auto I ever had was an Officer's Model. So very accurate that I used it to hunt squirrels. Although not nearly that accurate, the Colt Commander is the original carry big caliber pistol.
