That's what I thought. Cant remember the difference between the 70 and 80. Thank you for re-affirming my thought!
80 series has more involved trigger safety mechanism. Firing pin safety. It puts more involvement in the process and requires a bit more pressure on the trigger.
The newer Colts are just not that well made anymore. For the price you get so much more in an RO or a loaded.
I sold all my Colts.
