I recently purchased a M38 from 1968-1969. I absolutely love it. I got it at a really good price because the orignal owner had "upgraded" the cylinder release, trigger and hammer with gold ones. This pistol lives in my pocket so its not real important except the hammer being bright distracts because it contrast with the blued finish. I am about to order from S&W blued parts to replace. Is there anything I should know or avoid or also get. I have thought of getting a wolf spring kit just due to the age of the revolver. I dont think its been shot alot I just figure they are 30+ years old. What are your thoughts.
