I believe they are also an 80 series and the triggers suck as a result.
This is an overly broad statement. One of the fastest match shooters I know personally (and who also possesses several Joe Bonar built 1911's) runs a tuned up Colt with a Series 80 firing system with all parts intact, present, and accounted for. If you spend anytime on the 1911 forums you will read of plenty of folks with hotrodded 1911's with both Series 70 and Series 80 firing systems who will tell you they can't detect the difference.
