SO EASY!
review-star review-star review-star review-star review-star
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
review-star review-star review-star review-star review-star
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.

I received my spring kit fast; I installed kit and found the trigger spring too weak to return trigger properly at a slow pace. I reached out to M*CARBO and they sent a new spring fast and free. I installed spring and the trigger works flawlessly.

Very nice people. Good service! Springs worked great for my wife’s S&W 38 Special.
Quickest trigger job.
review-star review-star review-star review-star review-star
I installed the springs in less than five minutes and what a difference, trigger breaks smooth and clean at around five to six pounds. ( No trigger scale available).
So if you want a nice trigger on you're J frame just do you're self a favor and get this kit!
Lighter trigger pull.
review-star review-star review-star review-star review-star
I just bought and installed the trigger spring kit on a model 637 J Frame.. The double action trigger pull is a little lighter. Before the installation, the trigger pull was 10 1/2 - 11 lb. After the installation, it is a consistent and very smooth 8 1/2 lb. I didn't measure the single action before installation, but after installation, it breaks at just under 2 lb. Overall, I'm happy with the result. A 8 1/2 lb. trigger is plenty light for me in a carry gun.

The instructional video made the installation very easy.
