Is tuning the Marlin 39A trigger an easy job to do it yourself?

    Marlin made a model 37 back in the teens, a pump 22lR.
    Not sure about the A designation, never saw one marked that way sorry....
    Any chance you mean the 39 A lever action ??????

    Easy? I'd say yes, but it depends on your level of experience and comfort with such things. Mainsprings are cheap, and I'd consider shortening it half a coil at a time until you get the weight of pull you want or you start getting missfires and/or accuracy starts to head south from inconsistent ignition. If you use something like an Arkansas hardstone on the hammer notch and sear, just be real careful to not change any surface angles OR the amount of contact. The one other thing you might consider (my several 39's are all gone and my memory isn't good enough to get too specific here) would be to find a good place to install an overtravel adjustment screw. That, and don't try to go too light.
    Good luck,

    It is not difficult to slick up the Marlin 39 trigger.
    It is also not difficult to break your arm on a skateboard if you don't have experience with them.....but don't shy away...just be conservative and carefull.

    RCrosby gave very good advice, and this model gun can give you a crisp trigger fairly easily....

    How much wear does it have right now ?
    If little or modest, consider just 'polishing' the engaging surfaces to get a crisp break, then lighten the pull weight if you want. Get good stones and go slowly and carefully...(think foreplay).

    AND .....most everyone has messed up SOMETHING. IF you mess it up, replacement parts are not too pricey, but enough for you to remember your 'lesson'.

    Fine Rifles....ENJOY !

    If your 39A is a new rifle, give it some time and it will lighen up for you, I have an old one that has never had any work done on it and it has aquired it own trigger jop by usage. I have used Wolfe spring kits in revolvers and they work well and come in diffent tensions to let you tune your weapon with out having to cut coils, I don't know if Wolff supplies spring for your rifle, check their web site. http://www.gunsprings.com

    AS the guys have said- your goal is to POLISH the mating surfaces- NOT to remove metal. This is REALLY not the place for a Dremel! You can use a hard Arkansas stone, being VERY careful to keep same angles in all axis- your goal is to smooth the metal surfaces so they slide over each other without hanging on microscopic burrs. DO not use files, coarse stones, etc etc etc. It is a LOT easier to remove metal than to put it back.

    I bought a 39A Golden Mountie that the original owner had a 'smith do a trigger job on. He got the trigger to about 1-1/2lbs. It is almost too light, took some time to get use to it.

    If you are going to hunt with the 39A make sure you tell everyone that is with you that you have a 2 1/2 pound trigger and give them a chance not to go with you.
