Galling would be an issue between the trigger bar and connector if the steel was stainless enough to actually not rust.

I've been wondering how a machined 4140 trigger bar and striker would act.

These guns were designed to be built with stamped sheet metal parts and the consistency is terrible due to the nature of stamping.
