S&W J-Frame Trigger Spring Kit

I bought my fiance a S&W 38 Centennial J-frame and she loves it but struggles with the trigger pull. I was hesitant to attempt this trigger modification, although I'm fairly mechanical and built models as a youth. The video on their website was incredibly helpful and I simply watched each step, paused it and repeated it on my end. With proper tools like the bench block, shank tool and polishing kit, I was able to get this done in about 45 minutes. Just make sure you keep the parts organized during disassembly and don't misplace anything... oh, and don't overtighten during reassembly. I thought I had an issue with alignment while pulling the trigger before all of the housing screws were tightened, but once it was assembled correctly it's even smoother than before. My lady loves it now and feels even more confident shooting. Thanks M-Carbo... another great product!

 

Installed the M*CARBO S&W J-frame trigger spring kit on my S&W model 642 J-frame. Install took about 1/2 an hour only because it was my 1st time working on a revolver. If you are familiar with working on revolvers, it could easily be done in 15 minutes. The youtube video is very informative and easy to follow.
Before the kit was installed I measured the trigger pull at about 12 lbs. on average after 5 pulls. After the install, I am averaging around 7 lbs. 3 oz. per pull. A reduction of 4.5 to 5 lbs.
I shot it for the first time today and WOW, it felt so much easier to shoot. The reduced trigger pull made it much easier to stay on target. I was plannig on taking it back apart and polishing all of the friction points and seeing how much of a difference that makes but I'm not sure it needs that after shooting it. I would recommend this kit to anyone with a J-frame.
Now I'm thinking about doing a M*CARBO trigger spring kit on one of my Glocks. If they are as smooth as the J-frame kit, I'll put one on each of my Glocks.

Really great kit. I've never done anything more than clean and change the grips. MCARBO's video and kit took me through it—one shot. Really quite fun! The gun fires much more smoothly. Thanks gentlemen!

Own numerous Smith revolvers and have performed spring replacements and trigger jobs on all of them. Using my trigger pull scale after finishing yielded minimal results. Should have went with Wolff!

easy to install.lowered trigger pull by 4+ pounds on s&w 442 da only. much more manageable trigger pull

Parts were well packaged, video for removal/install great. Took 20 minutes!
