I think the old M1911A1s I worked on before we switched to the M9 were all pretty much worn out junk, but what do I know? I just repaired them. We definitely saw fewer M9s come through my shop after the switch than we did M1911s before. It was not even close. The only M9s that I remember working on were ECOD jobs that were crushed by tank turrets and stuff like that. M9s have been very accurate and very reliable in my experience. The biggest problem is that they are 9mms but that is what the military required. The only reliability issues I know of with M9s were early model slide failures that occurred after 20,000 rounds (beyond the specified life of the firearm) and feeding issues because the military decided to go cheap and bought non-Beretta magazines that did not do well in the sand. I believe that both problems have since been rectified. I personally own a couple of fairly high end 1911s and a stock civilian M9 (Beretta 92FS). I have not shot either 1911 in a couple of years but the 92FS goes to the range with me pretty much every time and I tend to shoot very well with it. YMMV.
