Easy to install went from over 7lb to just over 3lb I also installed short stroke trigger at the same time I used 10lb spring
The 3d printed fixture that hold firing spring during roll pin installation, works great. excellent design and use of 3d printing.
Ruger LCP Max Trigger Spring Kit and Ruger LCP & LCP II MAX Short Stroke Flat Trigger installed at the same time.
1st time out after installing both kits (10Lbs Trigger spring), failed to fire 5 rounds, then rechambered one round, it fired. Changed to the 12Lbs trigger spring. Fired every time.
Very nice trigger now.
This trigger kit was a wonderful upgrade to my pistol. It made a huge difference in the trigger pull and feel of my gun. It installed very easily and performed flawlessly. The install videos were helpful. This is a quality product from a quality company.
Made time yesterday to test the spring kit for my lcp max. The results were great, much better groupings. I am using the 12 lb hammer spring and the other guys red trigger (like the look). Have made other upgrades to this gun which make a big difference in its operation. I will be testing the 10 lb spring in the future, may like that one even better. I was more disappointed in the factory mags, springs worked great.
Installed the spring kit today and with a little polishing the trigger pull is now 4lbs. Haven't been able to shoot it yet but feels good.
The installation video was perfect, and I love the trigger; it is much better than the Galloway Sigurd that I replaced. The reset is excellent.
The stock trigger pull averages 6.9 lbs. I installed the 12 lb first, averaging 4.8 lbs. Then installed the 10 lb and averaged 3.97 lbs on the Wheeler gauge and 3.26 lbs on a Lyman gauge.
The range report today on the upgrades is they worked flawlessly. There was a mixture of my reloads 95-grain round nose lead and Speer Gold Dot 90-grain factory HP ammo.
The Max liked all the ammo and the best part was the greatly improved Mcarbo trigger reset. Follow-up shots were so much easier to keep on target, and the accuracy from 15 yards made me look like I knew what I was doing!
Thanks for making the Max a much better-feeling gun to shoot.
Had done the cz po-7 trigger kit successfully, was thinking that the lcp max would be harder because of its small size. No worries, excellent mcarbo video tutorial. Also installed the mcarbo short reset flat trigger and stainless steel guide rod. Installation went fairly easy, used the 10# hammer spring. Trigger pull reduced from 4# 3 oz to 2# 3 oz on my digital trigger gauge. Going to range test it tomorrow to see if I want to install the 12# hammer spring. PS: the annoying loud trigger clicking noise os gone.
Instructions were great for this product but be very careful removing the hammer spring cap. If you push the retainer tab in too far it will snap off. Fortunately Ruger sells replacements for $4. I tested both the 10lb and 12lb hammer springs. In my gun 10lb and 12lb springs reduced the TP from 7.5lb to 4.5 and 5.5lb respectively. However the 10lb spring could not be used even with Federal primers due to light strikes (about 1 in 10 to 20 rounds). I got light strikes with reloads with federal primers and also with factory Remington, Winchester, Federal and Cor Bon ammo.
So spring kit definitely lightened the trigger pull by a couple of pounds. I originally put the 10Lbs hammer spring in, but experience a lot of light primer strikes. Switched to the 12lbs springs and the gun has no issues.
I used the 10 pound spring which has my trigger pull at 3.5 pounds now. My groups are a lot better now.
Excellent product. Made a significant improvement in trigger pull (much lighter and smoother). The 12 lb. hammer spring also eliminated the pronounced "clink" from the stock spring when dry firing. I am inexperienced at gunsmithing work, so it took me considerably longer (1 hour) than the video to make the upgrade. The only difficulty I had was reinstalling the chassis in the frame. Inserting the trigger end first wouldn't allow the rear of the chassis to seat. After numerous tries, inserting the rear of the chassis first, then the trigger end did the trick. Haven't tested the firearm at the range yet. But based on my positive experience with M*Carbo thus far, I don't expect any problems.
I've bought a LOT of MCarbo parts over the years and have never been disappointed. They know what they are doing and as an example, including the 10# AND 12# spring set is a great idea. In my case I tried the 10# and found it wouldn't ignite the hard S&B primers. The 10# spring worked with other brands with softer primers but I swapped the 10# for the 12# spring.
MCarbo tech support confirmed this and told me the factory hammer spring is 15#.
Great quality springs, fit well. Easy to install. Used 12lb. spring as 10lb. Spring was too weak. Works very well. Must recommend
Installed the 10 pound spring and flat hammer at the same time. Watched the install video and had it done in about a half hour with no problems. Great improvement in trigger pull weight and reset. Well worth the money.
I also purchased mcarbo trigger what an improvement over stock parts .
