This was a great upgrade and fairly easy install thanks to video. Already had it taken apart while performing trigger install.
Spring kit for LCP Max.
review-star review-star review-star review-star review-star
My pistol went from almost a 7 lb. trigger pull to 4 1/2 with a smooth take up and minimal reset, or as little as an LCP can get. I used the 12 lb. hammer spring after reading about light strike issues with the 10 plus a 2 1/2 lb. trigger is too lite for pocket carry. Overall I couldn’t be happier with the setup.

With all the upgrades, it significantly improved the pistol. IMO use the 12lb spring, the 10lb one is too light for carry and doesn't feed all types of ammo. The 12lb spring gave me an average trigger pull in the mid-4lb range. The upgraded trigger can be set to have almost no travel, which was my issue with the stock gun. It also has a more noticeable reset than the stock trigger. It eliminates the annoying metallic "ping" sound when dry firing as well. From a non-gunsmith (but someone who tinkers) the video provided by this company is easy to follow. Make sure you buy the correct loctite and punches before disassembling the gun though. Just spend the extra money and get everything, feels like a pro tuned performance center gun now. Also, if you are replacing the recoil spring, make sure to put the original INNER spring back into the gun. The stock gun uses 2 recoil springs and the upgrade is only the outer spring.

Try to imagine the sick feeling of an everyday carry gun that can only shoot one or two bullets before it jams and is hard to clear.

That is the state of my Ruger LCP Max after installing the M*Carbo trigger, spring kit, takedown pin, guide rod, and recoil spring. I used the 10lb spring.

I followed the videos very carefully. I used all the right tools, and dry firing is smooth.

It is more accurate than before, but out of 9 attempted rounds, 3 failed to load all the way into the chamber, and one was seated in the chamber, but the hammer was not cocked.

I had to drop the mag to clear the three that jammed on the ramp.

All of the upgrades M-Carbo makes for the LCP Max are worth every penny and then some - there is simply no comparison between a factory LCP Max and one which has been M-Carbonated. If you’re on the fence, just do it.

As others have said, I suggest using the 12lb hammer spring. The 10lb spring makes for a lighter a trigger pull than I like to have for a pocket pistol, and rarely caused a light strike (only on loads with particularly hard primers - the majority of loads I tested worked 100% of the time). The 12lb spring is right on the money - smooth every time and no issues, ever. Another great set of offerings from M-Carbo.

Combined with the MCARBO Flat FacedTrigger, these springs are the frosting on the cake. I used the 12 lb hammer spring and set the take-up and reset where I wanted. It is a different pistol, from pretty decent to outstanding. Travel is smooth with a crisp break and short reset. Taken all together MCARBO's LCP Max upgrades take a very good pocket pistol to a whole new level. Their installation videos are VERY good and make the installation quick and easy.

I installed this spring kit along with the trigger and could not be happier with the results. now i have a great 3.5 pound trigger that is much easier to shoot. This tightened up my groups and gives me the confidence i need to have in a carry gun.
Fantastic Upgrade for LCP Max

The trigger went from what's expected from a pocket pistol of this size to something unexpected. Much crisper trigger break and the 12 pound spring is about perfect for this size handgun. Much better groupings after the addition. Thanks MCARBO for great upgrade products.

Question:
I installed trigger kit and the 12 pound spring kit. My gun now has a high failure rate. About 7 out of 10 rounds will fail to load. (It ejects fine) Typically, (6-7 rounds out of 10) the problem is that the slide does not go all the way forward, but about 2 out of 10 rounds actually fail to enter the breech. I have tried 3 different magazines and 4 ammo types (Ball, HP, and Hornady Critical Defense - with all giving the same results) I ordered the stronger recoil spring and was wondering if it may solve these issues? If the new recoil spring does not fix these issues, is there anything else that can be recommended? (The gun worked flawlessly prior to putting in the spring kit and trigger – although with the factory parts, it seemed to impact about 10” below point of aim. With the new parts, the point of impact is much closer to the point of aim at 5 yards) Also- the trigger really helped eliminate the trigger-slap (or pinch-feel) on my finger. It feels much better now (If I could just get the gun to function properly!) 😢 Thank you

I installed the short stroke trigger and the trigger spring kit (12# hammer, trigger return and firing pin). While I love how it feels I’m getting light strikes with multiple ammo brands. Trigger pull is coming in at about 3 lbs. What can I do to fix this?

Are you sure you changed the firing spring? That needs to be the lower pound weaker spring to prevent light strikes. Are you sure you put in the 12 blue instead of the 10 red?

You can use the firing pin spring and hammer spring and not the trigger return spring but you will not receive the full impact of the trigger pull. We do recommend using all of them because we designed the kit as a whole to work together.
