Was curious if there was an advantage in Carbon Steel vs. Stainless in small parts like firing pin stops, extractors etc. For example, will a WC bulletproof extractor hold tension better in one over the other? Will one be less prone to breaking over the other? Are their firing pin stops less likely to crack in a certain type of material? I do understand that a particular finish will match a particular firearm(cosmetic differences), but was just interested in material differences. Thanks in advance for the info.
