so easy

We got this for the ST9 since it seems all the Kahrs have the same firing configuration. The installation was super quick, I'm sure the "punch tools" are helpful, but not necessary. I was able to use our micro phillips head screwdriver to accomplish the same result. Make sure the paperclip you use is one of the bigger thicker gauge type.
It has made a huge difference in the pull tension, much smoother. I'm sure it will be easier to shoot now, haven't tried it out yet on the range.
Now if there was just a way to get the trigger to fire a little higher up so the action was less like a revolver

Made me Like my CM9

I've had my CM9 for a few years and for the most part it stayed in the safe. I tried to bond with it but the trigger pull was too different than my other pistols. After doing some research I can across M*Carbo. For $14.95 I thought why not. Install was easier after watching the video. Only took 15 minutes or so. It does make a difference in trigger pull. Same Loooong pull but the reduced weight makes it easier. Maybe the M*Carbo team could look at a trigger shoe slip on to make the pull feel shorter. Just a thought.


Awsome product

over all very happy I ordered this kit. The trigger is a night and day difference . The install is super easy took me 15 min.

Made a PM9 shoot good

For years now I have had a Kahr PM9 that I just could not learn to love because I could not shoot it as well as I thought I should. I also have a Kahr P45 that I shot well because it had a much better trigger when I bought it used. Finally I found the MCARBO trigger kit for the PM9. Reasonably priced and it worked. My PM9 had a 6.5lb trigger stock and this kit got it down to 4.5lb. Little guns are hard to shoot with a heavy trigger but now I shoot it quite well and am getting the accuracy that the gun was capable of delivering. I know Kahr triggers are supposed to be a safety factor but the pull is still long-just lighter and smoother and more "shootable" and I do not feel it is in any way unsafe. And thank you guys at MCARBO for the installation video. I could never get the striker back plate off before. Much better to remove the extractor and take that pressure off and then you can remove the backplate. I also purchased a second kit for a relative's CW9 and had the same good results. She also is shooting hers much better now.
