On the cylinder turning star ratchet? I put a moly paste or anti seeze. On the ratchet and the hand that turns it besides the cylinder stud, trigger stud, hammer studs. Plus any metal to metal contact moving parts. Don't forget to put it on the Sears too. Let nothing wearout.
I like my different caliber n frames to have as close to the same trigger pull. Keeping the triggers with the same smooth action allows me to switch revolvers and shoot them the same. My two new s&w m58 & m57 had to different feeling trigger let offs. Applying moly to the sears made them equal. Once moly is applied run the action 50 to 100 Times to burnish the moly in.
