Waveski, I would like to expand on what I said earlier. I used to shoot 1911’s in competitions. I learned how to do my own action jobs BUT I was a novice. In the beginning I replaced a lot of parts because I didn’t know what I was doing. I also created unsafe firing conditions because I didn’t know what I was doing. When I found I had created an unsafe situation (by dry firing - not with live ammo) I threw away the parts and started over. I also took a gunsmithing course on 1911’s at a work shop held locally by a professional gun smith. I took this course when I figured out the experimentation could be dangerous.
When it comes to my S&W revolvers I have always been happy with their actions do I never tamper or modify them. I do as I said above.
On my Ruger Vaqueros, I have owned 7, I changed springs and I do lightly, and I do mean lightly, honed the trigger interfacing surfaces with the finest Arkansas stones I have, but that is it.
If you aren’t experienced in working on revolvers I would recommend looking into getting a good manual for gunsmithing your particular brand and model. Honestly though, I would take it to a gunsmith. Tell them what you want. Have them explain the process and learn from them, but have them do the work for you. It’s not rocket science but it should be done properly and the result should be safe. Safety is most important.
Even though I do most of my own work I still rely on competent gun smiths. We need to keep these local folks in business and they can be a very valuable resource when you have questions, but they do not work for free. Give them some business and establish a relationship with them.
But please don’t use abrasives in your gun. Who ever told you this “school of thought” needs to go to school.
