    Awesome product! I highly recommend

    This is a great upgrade. I bought a used 642 for $170 bucks! Couldn’t beat it. I got a new pistol grip and got this spring kit so my wife could shoot it. It was a simple gift for her.

    The original pull was about 11.5 lbs and installing this kit brought the pull to just over 8 lbs. About a 30% reduction, maybe a hair more on some pulls. It’s a very crisp and clean trigger pull now.

    The video on this page is spot on. My wife and I just watched the video, paused at intervals and did the work together. Great job on the video.

    I’ll be back for more from MCARBO as the need/want arises.

    A bonus: They mean it when they said they fulfill orders quick. And the actual shipping was only a couple of days thanks to the service provider.

    OK. S&W Lady Smith J Frame 642-2.

    OEM pull was a billion lbs. Seriously, my wife could not hold the gun with two hands and keep the muzzle still. For that matter neither could I! Installed a competitors kit which helped a bit but did result in a few dry fires and still the gun was hard to steady while firing.

    Enter the MCARBO Kit! Wow! Wife can one hand the gun now with little muzzle movement and with 2 hands nine! In other words, she is hitting center mass either way! Amazing how nice the gun feels now and has regained its place next to her at night.

    The install video is how all instructional videos should be done and is a very straightforward install.

    Well done Brotherhood!

    I only installed two springs from this kit and it made a big difference. I don’t have a trigger pull gauge but it is definitely better. I did the install myself and it was quick and easy.
    Very Nice

    My results were almost exactly in line with what they advertise. Installed this kit on a S&W Model 60-10. Before installation, DA pull was 11.5 lbs, SA was 2.5. After installation, DA is 8.5, SA is slightly under 2. The trigger feels great. Installation was fairly easy following the video instructions.

    I just installed the spring kit in my model 37. The double went from 12 to 9 lbs. The single action went from 3 to around 2 lbs. Very happy with this kit.
    SO EASY!

    Lightening the trigger pull is one of the easiest ways to improve your accuracy, and this took less than 10 minutes on my kitchen table. This review is from a gun-owning liberal (yes, we exist!)
    great video

    I bought my Model 36 many years ago(for 239 dollars) and I never liked the trigger pull in double action mode. And single action is too dangerous. I passed this gun on to replace a glock in my family BUT..... same horrible trigger pull. Then I read that the trigger pull has always been hated by model 36 owners. I saw the website for Mcarbo but more importantly watched the video(several times). The video is well-done and easy to follow so the new springs along with hogue grips and Norma self-defense ammo now make for a perfect conceal/carry weapon.

    Have two J Frame S&Ws, and swapped out the Hammer Springs. Need to get a tool to swap the Trigger Return Springs, but already seen a better DA trigger pull. In SA, the difference is even more noticeable. Please note that a Roll Pin Punch (with a centering dimple) doesn't work if you try to use it to swap the Trigger Return Spring.
