Difference
Any .45,
I am no expert on Colt .45 acp's, but the big rumor around when Colt
switched design fron the Series '70 to the Series '80 was that they screwed
up the trigger-pull.
I have owned a Series '70 since 1972. I had a trigger-job done on it in
1973, making it a crisp 4 lb. pull. It has been that way for the last 30
years.
People I know who have 'Series 80's claim that the extra linkage to the
firing pin block creates a trigger-pull that is undesireable, at best.
I have had people tell me that a trigger-job on a Series 80 was a waist
of time and money, because the trigger was inherently "bad".
Any good rumor, of course, is worth what it cost. But that was the
story going around 'back in the day'.
I have a 'Series 70'. I have never fired a Series 80'. I'm only repeating
what I have heard.
