Kahr trigger spring kit

Ordered this kit for a P9. While the P9 already has a nice trigger pull weight, I thought I’d try this and see if I got an improvement.
Quite pleasantly surprised (pleased) with the results. Went from just over 5lb pull to right at 4. Didn’t take but a few minutes to install (took longer to clean slide after disassembly). Really effective kit for the Kahr pistols.

Installed in my K-40

I don't have a trigger scale, but the trigger is feels much better. The installation is simple, the video provided is great and easy to follow. Highly recommended.

Kahr CW45

I installed a trigger kit and stainless striker guide in my new Kahr CW45. The result is a lighter, smoother trigger pull. This is my second Kahr that I have installed these same parts. The result was excellent too. The installation was easy after viewing MCARBO's video. I would absolutely recommend this upgrade.


Made something already good even better!

This is a great kit. Installed easily and dropped my CW9 down to an even 4lbs. I prefer the double action style trigger for daily carry and this really puts its weight in a easy to shoot range without compromising safety. Great kit!


K9, MK9, PM9 Spring Kit and SS Striker Guide

This spring kit made my Kahrs into real hot rods. 4.5 lbs. pull for the K9, 3.7 lbs. pull for the MK9 and PM9. Chris's video makes the whole process very clear. I really like the SS Striker Guide as well...it's in all three pistols.

I suggest a change to the video, though. Removing the extractor at the front is a rather difficult process. This set of instructions (which, unfortunately, I found after struggling with the extractor on the MK9 today) really is a better technique for stripping the slide:
Useful info on slide lubrication technique as well.

As usual, M*Carbo delivers! Great products, excellent installation videos.
