10# spring
I got the max on Monday and installed the kit on Tuesday. Like many of my guns I buy I don’t shoot until I put the upgrades in. Same in this instance. I don’t know what it would have shot like before installing the kit. I also installed the new flat trigger kit at the same time. I can say the dry fire noise was horrendous very noisy. So glad I changed that. It is now quieter and with a smoother trigger pull. I did however notice that firing the weapon I need to squeeze the weapon firmly in my hand or I will get a none fired round. Now holding firmly I can rapid fire without a problem. Like always I feel my upgrades like these has made me a better weapon.
Light primer strikes
Installed 12lb trigger spring. Left stock firing pin spring in. Greatly redudced trigger pull, but completley failed to fire anything I tried. If you depend on the ruger max to protect yourself, do not install this garbage.
Outstanding!
Gets rid of the annoying "clang" noise when dry firing. Kit was super easy to install and everything fit just like stock. Can't wait to get this on the range to test out my easy pull trigger setup.
Worth It
I installed this at the same time as all other available springs and trigger, and together, they really brought the pistol up to another level. It's easier to control which adds to my confidence. Install was pretty easy with their videos and instructions; all in, it took less than half an hour. I chose the 12# spring just incase I get a hard primer. My range has steel targets set up at 15-18 yards, and I can easily put all 12 rounds on a 1/3 torso with half second splits.
Excellent upgrade
Trigger is sub 5lbs now which greatly helped with shot placement. Awesome bang for your buck,as usual, from Mcarbo!
Much better trigger feel and hammer sound.
Firing pin spring too weak
See pic. I noticed when installing the firing pin spring that it was much weaker than the stock one. I was obviously right but I wish I didn't even put it in.
Best upgrade I've ever made!
The difference is trigger pull weight and feel is night & day! After reading reviews of this spring kit, I automatically opted for the 12lb spring over the 10lb, as there were many reports of light primer strikes with the 10lb. So, I expected to have a minimal change in trigger pull. Boy, was I wrong! Nobody can believe this is the same gun as before. My accuracy was garbage prior to this upgrade, primarily due to the amount of force required to pull the trigger. It's by no means a hair-trigger, but feels like it should from the factory. Also to note, I did previously replace the trigger, recoil spring, and guide rod with another brand. While those upgrades helped somewhat, they were nothing compared to the change made by this spring kit. The installation video was also great! Thanks M*Carbo for transforming my summer EDC into something I can count on!
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?
Would installing a 13 pound recoil spring add any benefit when using the MCARBO spring kit?

The recoil spring will just prevent the slide from slamming back too quickly. This spring kit has everything to do with trigger pull.
why do you need to replace the trigger spring if you dont replace the trigger?
If you like the full benefit of the kit, we recommend replacing all the springs
Does the weaker firing pin spring in the LCP MAX kit affect the safety of the pistol if dropped?

Ruger LCP Max Trigger Spring Kit is drop Tested according to SAAMI Standard Z299.5 rating (12" & 48").
Is the trigger return spring lighter or heavier than the oem spring? What does it change in the feel? Also can it be used independently from the other springs in this kit?
Can I use just the firing pin spring and hammer spring in the kit and keep the factory trigger return spring? Will that effect reliability at all? I assume this will still reduce the trigger pull some amount…correct?
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.
What is the stock poundage rate of the firing pin, hammer and trigger return springs rated at?
November 11, 2022 10:12 AM
The stock trigger is about 7 pounds.
Does this spring kit also work with the LCP II?
