    I have been working the trigger over on a j frame and it started with a trigger around 17 lbs.

    After disassembly, very light rebound slide polish, oiled up and dry fired it was smoother and around 15.5 lbs.

    New rebound slide spring and it is now around 11-12 lbs.

    My goal was 10lbs or under and 100 percent reliable with factory mainspring. Maybe I am a dreamer idk?

    Next step is a more through polish of internals and shimming the hammer and trigger from the sides. Then I think I would call it done.

    Have any ideas/comments/suggestions?

    I use a 13# rebound spring and a lighter than stock mainspring from brownells in their spring kit for around 8-9 # pull on j frames. TT

  3. I did a few using the Wolff reduced power set, reliable ignition, light and smooth.

    I have one J Smith that is fine with a Wolff RP spring set but another that demands a factory mainspring for reliable ignition. All it got was a slightly softer rebound spring.

    How rough was your rebound slide? I ask because I have a Smith 637 J frame that I am going to be doing the same slicking up to. Also another quick question; what direction does the ejector unscrew? I had the gun apart last night but didn't want to "force" it the wrong way. Is there a trick to getting this apart without marring the knurling ont the end?

    Good video for beginners.

    One of my sayings among friends is "Life is too short to put up with bad triggers".

    Biggest mistake is cutting springs. Buy after market kits, they are cheap!

    I'm a little concern when you say you are planning on shimming the hammer and trigger. Shimming should not be needed on a J frame meant to be carried for self defense and IF it was you have bigger problems than a DIY trigger job.

    Since you asked, my advice is:

    Polish (do not remove metal!) all metal to metal contact surfaces.

    Clean and lubrucate parts.

    Replace factory springs with after market kits (Wolfe's or Willson from Brownell or Midway)

    You could look up Apex Tactical Specialties (I think that's the name). They have a J-frame kit that's supposed to get the trigger pull down to 9lbs with duty/carry reliability. It's only for newer J-frames with the frame-mounted firing pin. If I remember correctly it costs about $25.00. I don't have any firsthand experience with it, though.
