Think it's worth it to install those?

I've had two Series-80 style 1911s. Taurus and genuine Colt. I never had a problem with the firing pin safety system on either pistol but I've never done a really light trigger.
My Colt was 4.25lb, built for plate/pin shooting. I polished the factory firing pin safety lever & that's it. Been a few years since I've had this pistol...an ex-GF still owns it though.

The Taurus is quite a bit lighter @ 3.25lb. I tried the Taurus both with and without the firing pin safety parts installed and didn't get more than a couple ounces difference in pull weight or smoothness.
I just polished the factory parts (the original lever and new pins), reinstalled em, and never gave em another thought.
