Not to get too much off on a tangent, but I have never used a encountered a 1911 that was really stone-cold reliable. My 1911 is probably my most-shot pistol, but I don't have illusions about it just because of that.
I posted this in a different thread, but it bears repeating:

I looked up some information on the outcome of the XM9 and XM10 pistol trials (the trials how we ultimately wound up with the Beretta M9 as our service pistol), and I was somewhat surprised at how poorly the 1911 performed. In the 1981 trial, the 1911 had a mean round between operational failure (from what I understand in the report, this would include a parts breakage or jam) of 165 rounds. Basically no guns passed the 1981 criteria and the Beretta and SIG had 158 and 209 rounds respectively. During the 1984 testing, the 1911 came in at 162 rounds. By comparison, the Beretta and SIG had jumped to 1,750 and 2,877 respectively.
The somewhat shocking-to-me outcome of this failure rate is that these particular 1911s in this particular test only had 95% probability of making it through a 7-round magazine without interruption. The SIG and Beretta were both 99% likely to make it through a 15 round magazine without interruption. By comparison, the 1911 was 90% for 15 rounds.
