    j frame trigger job

    Well I bought a 642 Friday night.
    The triggers a little stiff (guessing 15lbs)
    Has anyone used the Wolff reduced hammer springs.
    Can you get reliablity from the 8 pound?
    Let me know you experience
    I will do a range report and post pics later!
    Thanks

    Before you start changing springs I suggest you get some snap caps and dry fire that snub till you're blue in the face.
    Then rethink the "spring" idea.

    ditto!

    I did just that with my 637 a couple of years ago and it smoothed down to around 4 pounds SA and around 6-7 DA...smooth as silk

    LOTS of dry firing. I still dump the rounds occassionally and "wall drill" dry fire trying to teach my muscles good trigger control. It will get smoother on it's own.

    You can get reliable function from the reduced spring kits. It's one of the more requested jobs in the gunshop where I work. I don't like to do trigger jobs until they've had at least 200 rounds through them, and 500 would be better. Dry fire helps a lot too. The mechanism isn't that hard to work on, it's pretty simple and it's hard to screw up the DAO guns. The safe choice, and what we recommend to everybody, is to test fire a hundred rounds in addition to what we fire to confirm reliability after the work is done. For cost purposes we only fire 20 rounds.

    opie,

    I have the Wolf kit in my 340.

    The kit comes with a couple different weights of each spring.

    To ensure reliability (I carry mine constantly) I polished all the
    engagement surfaces, but I left the hammer spring alone.

    I only changed out the trigger return spring to a lighter one.

    I'm no gunsmith, so take my opinion for what it's worth, but the
    two main springs you are 'pulling against' in the DAO action are the
    trigger return and hammer springs.

    My trigger spring was very stiff, and I used the next-to-lightest
    spring that came with the kit. I know it is possible to 'outrun' the
    trigger return, but I don't think I can even get back on target fast
    enough to outrun the lightest one. (so I went with the next one
    'up' just to be sure)

    This (along with the polish) helped mine out greatly.

    I sent my 642 to S&W for a trigger job. I think it was $75. Any way it made a big improvement in the pull and smothness of the trigger. I am well pleased.

    It will get better with time. But it takes quiet a bit of time. The dryfire/snapcap suggestion is good start.

    My 442 came with a similar trigger (14-16lb range). I ordered the spring (8 lb.) and dry fired like crazy until it arrived. It got a bit smoother, but not any lighter. It took the spring replacement to make the pull weight tolerable.

    Pull is still about 10-11 pounds which feels a world better. Unfortunately, I haven't been able to get to the range (snow is finally melting out there, but now time is an issue) to test reliability yet.

    I ordered the Wolf spring kit and put in the lightest springs right off the bat so I could check for reliablity. It was the best decision I have ever made. The trigger pull changed dramatically. I never measured it but I know my ten year old had to use two hands to fire it before the swap and now he can help me dry fire it when I get tired using one hand at a time. I have NEVER had a lite strike and I would do it over in a heartbeat. I did spend several hours on my hands and knees looking for springs, so be careful

    That's cool. Do you know what they did to it?

    The trigger rebound spring is lots heavier than it needs to be as installed at the factory.
    In short...yes, you can switch out both springs for lighter springs and still have 100% reliable ignition.

    i was told by a local smith that a polish job will make it smoother but the only way to lighten pull is to change springs and I know i will get flamed for this butI am unwilling to risk a misfire and wont change the springs.

    My experience with revolver springs goes back many years. I have a S&W 686 plus, a model 620, I had two 629's and I had trigger jobs on all of them by Mag-Na-Port. I had them reduce the weight on the triggers and on the 686 plus I planned on using for target shooting only. I don't know the weight but I can slow pull the trigger on the 686 and 620 with no effort at all and maintain the aim on the target.

    So, bottom line. I've never had a misfire with any of these guns, with factory ammo. I'm no expert but, I believe the talk about getting too light is a lot of rumor. I've never been in a gun fight so I can't speak to that. But I do practice double taps at the range and have no issues.

    I have a S&W mod 60, J frame and I have the Wolff kit in it, with the lightest springs available. Again no misfires. I will send it to Mag-Na-Port when I get the money and have them lighten it more and do a trigger job.

    Dry firing does help smooth out the trigger and most of the dry firing helps build your ability to pull the trigger, I believe. What I mean by this is after five or six hundred dry fires, you'll get more adjusted to the trigger.

    Personally, I have no hesitation in reducing the springs on my Smiths.
