IMHO, there are problems with the 700 trigger. One is that excessive wear in the older mechanism can result in failure of sear reset, and the gun firing when the safety is removed.
BUT, the biggest problem is that a zillion idiots just had to take screwdrivers, files, bench grinders and everything else to that trigger to "improve" it, even though it was the best trigger ever put on a standard sporting rifle. There were even web sites (now seemingly gone - wonder why?) telling the fools exactly what to file, grind, adjust or hammer on to make the trigger "better". Too many people did as advised, and the a$$holes who gave the "advice" won't accept any responsibility. It is just fortunate that more people were not injured or killed.
