If you understand how the Colt 80 series safety works you can make the trigger every bit as good as a 70 series. I have spoken to a few highly regarded 1911 smiths about this over the years. Don Williams, Harrison, Garthwaite, Cogan, West & Yost all work on 80 series pistols and can make excellent bulleye or fighting pistols out of an 80 series gun. I personally prefer 70 series guns but have a few 80s in the safe. I believe that people who think you cannot have a top tier trigger on a 80 series simply have not shot one beyond as they come straight from the factory. A good smith can take the 80 series to near perfection just like they can take a 70 series and do the same. IMHO YMMV
