Thanks Jim for the advice. Guess I'll limit dis-assembly to the cylinder to clean in the extractor area.You could stone the bearing surfaces, but on those guns they were case hardened so stoning my cut through the hardening and leave the parts subject to wear. You can also file/grind the sides of the mainspring (hammer spring) to reduce the trigger pull, but that may result in misfires if carried too far. I strongly suggest you not try to adjust the trigger pull or even disassemble the revolver unless you have experience with them. Those guns come apart easy and go together hard.
