At the first firing of my new PT1911 a couple of weeks ago it was shooting about 4" low at 10 yards. I called Taurus and asked for a lower front sight. At first I was told they don't have a lower sight but after pressing the issue they agreed to send one out. Called today to check the status of the order and was told they are out of stock and don't know when they will come in. I also inquired about the extractor problem and they confirmed that it does exist but they couldn't give me the range of serial numbers affected. They did say that most failures occur within the first 100 rounds. I've put 120 through it and no problems yet. Anyone have afailure after 100 rounds?
