    How many have done/had trigger work on your sub-2000 ?
    I installed the MCarbo spring kit but after seeing how rough the contact points were I polished them, reassembled and so much better, but still a very long pull.
    Used a marker I covered the contact surfaces, reassembled and dry fired a few times, took it out and seen how much the hammer contacted the sear, filed off 80% of the hammers contact edge, repolished, dab of grease and reassembled, I will show trigger pull tests when I get back to work and use the gauge but man oh man is this sooo much better. Vast improvement over stock.

    Still not a target trigger, but for a combat/defense weapon it's perfect .

    Dangerous trigger modification filing 80% or anything off the contact edges. Done bump and drop testing?

    Chuck is correct. There is a very fine line between a soft trigger and a fully automatic weapon with this specific trigger.

    I did the 80% over doing a little at a time, checking each as I went. This thing still has lots of contact on the sear.
    And yes full battery of tests this is not my first trigger job.
    I do work on guns for a living if you must know.

    Not necessarily MUST know. But if you are going to describe mods like this in a gun forum you have been a member of for less than a month you are likely to get some cautionary advice. It's the nature of the beast. ;)

    Crazy stuff. I just lightly polished the hammer & sear contact surfaces to get rid of that 2 stage trigger feel. It worked perfect on both of mine.
    The trigger on my 40 cal. is better than my 9mm. I am not sure why?

    I understand, I'm new here as this is my first Kel-Tec. About to get it all set up to the way I want it. Cerakoted, trigger, removed sights and mounted red dot.
    Just need to fab a shield to help with hot gas as I'm a lefty.

    I'm thinking about velcro attachment but will start working on things this weekend. I'll post pics of the end result.

    Yes I have. After installing the MCARBO trigger kit I found that the take up was very excessive. I know they are working on an upgrade trigger bar, but not wanting to wait, I decided to make my own. After examining the action, I determined the shortcomings of the trigger bar and why the take up is horrible: 32872545_146447456212169_205770933963587584_o.jpg

    The sear notch wants to ride up the inside radius combined with the fact the "gap" is excessive which allows all that travel. I first bought a $5 replacement from KelTec then went to work using the new one as a template. Using some thin steel sheetstock, I cut out a rough shape:

    Then began the tedious task of filing...then filing...then filing some more:
    20180522_110241.jpg

    Inside the notch where the sear pin rides, special attention was used to make sure all burrs and filing scratches were removed to insure a smooth action. Emery cloth cut into thin strips was used to sand this area to a mirror finish. 320 grit ending with 2000 grit was used:

    Next, the whole bar was sanded smooth and polished:

    When stacked ontop of one another we can see the tiny bit of material that was "added" to the factory bar:

    The only thing left to do is to bend the tabs over and do a heat treatment. Everything was done by hand with the exception of drilling out the holes which was done with a drill press..I'm confident the take up will be reduces significantly, and the trigger pull will be much more positive. If its an epic failure, then I'm out only $5 and time..


    All Done.....

    I hope it works. You have a lot more patience than me.

    I'll be interested in a comparison between your's and MCarbo's aftermarket trigger bar. Word is we can look forward to a 6.19 release from MCarbo.

    ...for the evaluation units...Im not willing to wait that long..Have you heard what the final $$$$ will be? Keeping in mind a factory part is only $5

    I just got done installing the flat trigger and the spring kit on my G2. I polished the area of the trigger and sear where they meet. So much nicer now.
