The only differences is the added safety features that are put on a series 80 pistol.
The pistol can drop as a series 70 and go off. It moving parts are only 4 parts the upper and lowers levers and the firing pin plunger and spring.

Note the new throat configuration on the barrel on the right. Believe it or not, this new setup actually improves reliability and reduces the chances of case blowout by better supporting the case head. All current-production Colts use this new configuration, including the new Series 70 pistols. An original GI barrel is at the far left, while a normal "throated" barrel is shown in the middle for comparison.
