In a nutshell, what are the differences and is there any reason I should avoid a Series 80 lower?

I am looking at a Combat Commander stainless Series 80 lower with a pre-Series 80 blued slide.

Thanks in advance,

Series 80 added the firing pin safety. No need to avoid them. some say you get a better trigger from a 70s I own many of both and cant tell the difference
in trigger on either. One of my favorite is a Series 80 Govt. Had a 3.5lb trigger done and some novac sights. Hits where I aim.

Who did your trigger work and Novak sight installation?

I will pick this one up on Sunday and probably change to a flat mainspring housing and maybe go with a smaller beaver tail - I have small hands and never got a hammer bite from any Commander I have ever fired.

Not going to do anything trigger-wise until I've shot it some to see how it does, but tritium Novaks are a must.

Thanks!

If the hammer is lowered with a live round in the chamber on a pre-series 80 (which is dumb to do in a 1911 style firearm) a blow to the hammer is more likely to discharge the firearm. The series 80 employs a firing pin safety.

I think I found a good explanation here...

The hammer presses directly against the FPS when the hammer is down. There's no room for the hammer to move if smacked hard.

What can happen is if a Pre-80 Series is dropped muzzle down with a round in the chamber, it can potentially go off due to the firing pins momentum causing it to hit the primer. The Series 80 system doesn't allow the firing pin to move unless the trigger is pulled.
