    Did a trigger job last night!

    Bought a 642 J frame 3 weeks ago and wasnt real happy with the trigger.
    So I ordered the Wolff spring kit for it and it arrives yesterday.
    So nervously I grabbed the screw driver, digital camera and other tools (Dremmel, plactic hammer etc)
    I previously watched a you tube video on removing the internal lock from a 640.
    So off I went taking it apart (taking pictures every step,just in case)
    First I have to say that smith and wesson probably could do a better job in the maching process, but hey its 2010 and quality control aint what it used to be.
    So I removed the hammer strut
    Then the hammer
    Then the cylinder latch assembly.
    I removed the internal lock lever (since i was there ,why not)
    I then degreased all parts.
    I then took the hammer spring off the strut. I polished with dremmel and felt pad, the hammer strut where ever it made contact with any other parts.
    I then put the 8 lbs spring on it and pinned it to hold,
    I then removed the trigger rebound spring and assembly.
    I then polished the contacts of where the hammer contacts it as well as the bottom slides and contacts the frame.
    I then installed the reduced spring and re-installed the assembly.
    I then re-installed all parts lubing liberally with anti seizing gun grease.
    Re-installed the side plate and grips.
    The trigger pulled improved (I have no scale) but you could tell a difference (But not dramatic)
    So its off to the range Saturday with my wife for reliabilty testing.
    Anyway sorry for the long post but I wanted to add this just in case any others were thinking of doing it in the future.
    I will post pictures of Saturdays range test.
    By the way, I only had one mishap. While installing the hammer sping my fingers slipped and shoot the little cap at 75 MPH across the room.
    Fortunately I found it (yea)
    FYI

    Did you install a lighter trigger rebound spring? That's where you should really notice a lighter trigger pull.

    Yes, but it was strange
    The kit came with 3 reduced power springs , however I think that wolff may have mispackaged them.
    The shortest one was actually labeled the middle poundage one.
    They were only a pound a part so I installed the middle one (as labeled) but I think it was the lightest.
    As stated it is better but not dramatic but the range time will help.
    I like the little gun , real light and surprisingly accurate (shot it prior to the kit install)
    I'm really excited about hitting the range this week.
    I have ordered (my cousin works at a gun shop) the speed strips and I may go with a fanny pack holster (and an additional pocket holster for cargo shorts carry)

    I have a 340 for pocket carry in my cargo shorts, front pocket. It is an awesome little weapon.

    That's correct. The length doesn't determine the pressure, the amount of "spring" in the coil does.

    I installed a set in my Taurus 85UL and OH MY GAWD! It was a totally different gun! These spring sets are worth it if you're faced with a revolver with a heavy pull.

    It's an easy job almost anyone can do. As the OP posted, make notes, take pictures, make notes, be careful, and work slow.

    Go to the Wolff website. Look under "revolvers". There will be a "Spring Pack" listing for the Taurus 85 and others. This gives you 3 weight options with the trigger return and hammer spring. I installed the lightest of both.

    I've disassembled two CZ-82s so far but reassembled six! Seems something always falls out three parts ago and won't go in until taken apart again. And the worst part is the hammer spring strut. It goes in first because it won't fit in otherwise. Yet it fell out three times (?), wouldn't fall back in to save my life, resulting in more take-downs. I'll consider myself an expert when I disassemble once and reassemble only twice!

    I may have to do this with my 442. I've not really had issue with the heavy pull, but if you can improve the feel then why not. Is there any reason not to?

    Work involving tiny high-pressure springs is often best performed with your hands and the parts inside a ziplock bag.

    BugDude, some argue that reliability is jeopardized if you alter the springs.
    Im hitting the range tomorrow to make sure it hasnt been.
    Also Ive heard that if you lighten the rebound spring too much you can out run it when rapid firing.
    Stock wasnt horrible but the better the trigger the better shot I am.
    I was really impressed with the LCR trigger, but the gun looks bigger than the j frame.
    Good luck if you decide to do it.
    Its really easy
