1911s are by far the best platform out there but they arent cheap. As far failures go if you are going to use it to protect your life or family make sure to have a reliability package performed by a good gunsmith.
1911s are like Tacomas good from the factory but better after mods. My personal preference is a Colt Commander.
I had a coworker a few years back that owned a Colt 10mm auto. Beautiful pistol. He had never shot it and kept it in his night stand with a loaded clip for personal defense.
Finally talked him into going shooting with me one day. On the first shot - the slide stuck and stove-piped the spent shell. That really opened his eyes.
I took it home with me and did a tune-up - it worked flawlessly after that. New guns, especially autos can be very tight and not ready for 'action'.
