Great question, Danny. The hammer, decocker, and trigger are all nickel-plated to match the slide's finish. I've owned one of these...great guns! You'll enjoy it.

The parts are Nickle There is no good picture of this gun on the bersa web site the on that is ther shows a nickel safety, hammer and decocker but says new picture coming soon https://bersa.eagleimportsinc.com/bersa/firearms/thunder-plus/models/thunder-380-plus The 7 round thunder shows the blue parts but this is the 15 round thunder Plus and all pictures I find of it show the nickel I suggest contacting bersa to be 100% sure Phone: (732) 493-0333
