I bought the Colt new at a gun show in February 2011. It was back at Colt twice for repairs in the first 90 days, before the gun made it through the first 400 rounds. It never made it through a single magazine without stove-piping and then the plunger tube came unstaked. It seemed to run alright after the second trip to Colt CS and an angry letter, but I didn't trust it. The next time it had a feeding issue, I sold it. This was my first Colt and I was extremely disappointed. I replaced it with a SIG 1911 Fastback, which has never had an issue.
