Best method for polishing trigger(s)
Aside from getting new trigger parts or new trigger entirely, I know polishing your engagement areas in your trigger will help lower the pull weight. But I haven't seen any "best methods" to do that. What material do you use? Do you use a tool such as a dremel (with a cloth tip of some sort) to do it or by hand?

Polishing is not about reducing the trigger pull. It's about making the trigger smooth.
No Dremel(just a brand name like Kleenex. If attachments say Dremel on the package they just cost more.) or any rotary tools with grinding/stoning tools. A cloth wheel and jeweler's rouge is used for polishing. Low speeds. THOU SHALT WEAR EYE PROTECTION! There's a bit of an art to it too. Starting with a light touch.

Rotary grinding/polishing tools should be banned from the same room as firearms. For trigger polishing you are talking about smoothing the engagement surfaces. Use a fine small square stone, no oil, and be dang careful not to alter the engagement angles. Lots of good guns have been screwed up by Bubba. There are jigs available, particularly for handguns, that keep you from altering engagement angles, they can be critical. GW

Think about what it is you are trying to achieve.
You have a sear with a face that was supposedly cut to a precise angle squarely across the sear. Depending on the gun design,you may have a hammer notch,cut with similar precision in a machine. These two surfaces should precisely mate across the width of the hammer and sear. Do you,or OHeir,really believe you will "improve" surface finish by spinning some grit filled ball of rags over these surfaces? What you must preserve is precise geometric form. Rags (buffs) don't do that. Its done with precisely shaped hard stones. Generally ceramic,these days,though high grade hard Arkansas stones work well. These stones are controlled for a square,straight stroke and precise angle by a sear jig. I have these tools,and 20X magnification to set them up. I get my final "shine" off of a black Arkansas stone that is dressed true on a DMT diamond plate. No rags,no felt,no Dremel. OK,I have been known to use an optical comparator and a surface grinder,too. Rounding,eroding,washing out sear and notch geometry reduces engagement surface and tends to make dangerous triggers. "Polished shiny" is ONLY beneficial when precise geometric form is maintained. That is done with precise hard stones that are controlled ,not a formless buff held in the free hand |

For myself there is only one real way to polish trigger's. Take it to a good gunsmith!

Dremel with a cotton wheel and Flitz or Mother’s.

Let me be gentle about this-
DO NOT USE DREMELS OR OTHER MOTORIZED TOOLS ON TRIGGER MECHANISMS! |

I say this as someone who thought he was going to be a world class gunsmith 15-20 years ago and I jumped headfirst into a bunch of projects that... well... didn't turn out so great. I've had to replace a number of parts that I butchered in my younger days. So I'm not insulting you, I've been there. |

Hard Arkansas Stones.
I use Nortons. They are far from cheap. And they'll shatter if dropped. But they'll also last a lifetime in the hands of someone that only does a little stoning every couple years. As mentioned by others, a rotary tool can be useful for certain firearm-related tasks, but they don't belong near sear/trigger engagement surfaces that are intended to be kept safe and precise.
