Series 80 is not a big issue. All modern handguns have some form of passive firing pin block. Does it add parts? Yes, four in the case of the Colt/Para Series 80 guns. Is it a problem to disassemble? No, just a small something to learn. Easy after the third go round. The big advantage is, even in the unlikely event that a sear or hammer fails - the gun cannot discharge unless the trigger is being held back, period. This is a Good Thing.
Tips - To prevent loss of small parts on any mechanism you are new to - put the item in a large, clear plastic bag, or just work carefully as you go and be aware that if the part is backed by a spring, it can head out to parts unknown - but only if you let it.
As for the firing pin lock plunger spring - put a heavy grease in the bottom of the plunger cup with a toothpick - you will never lose the spring again!
Important points - DO NOT imstall or change the setting of the set screw in the so called "Match" Triggers - unless or until you understand how this affects trigger overtravel and sear release/firing pin plunger clearance. Misadjusting this screw can prevent either a Series 70 or a Series 80 from firing!
Minor but important stuff - but the 1911 is not for dolts, in either form. I'm sure you will find it a non-issue in short order - as most of us have.
Warmly, Col. Colt
