Was wondering if anyone has installed the new trigger spring kit for the LCP Max, and if so, would love to hear your feedback on shooting the Max before/after installation. Thanks

Yes, and I posted a review on the Mcarbo website under the spring kit parts section.

Thanks for letting me know. I think I’ll order it and do exactly what you’ve done. I currently have the Galloway Sigurd, but will try the Mcarbo trigger. I like the fact they drilled a hole in the safety so you can push the pin out with a hex key instead of removing the safety blade to access removal of the pin. Great thinking there.

Installed it on mine had ordered it the day it was released. The install video is great and recommend watching it before installing. Like the fact when dry firing the spring doesn’t have that annoying twangy sound. I installed the 12lb spring as its my carry gun don’t want any light strikes. Now we just need a way to remove the slide rattling too much play. I also installed the new trigger at same time. No more bite of the finger. So together a real nice trigger pull with no takeup. One not thou you need a slightly bigger set screw a real bitch to adjust with that tiny wrench. All in all very happy with it.

I installed the spring set and trigger upgrade. Only test fired once but I had about 1 in 10 failure to fire. Light strikes. I need to figure out which spring is causing that issue.
I do like the improvement. I won’t be using it for carry until I have this issue resolved.

The 10 and 12 lb springs you get with the spring kit are color coded. I did the spring and trigger upgrade the other day, and will be going to the range to test it out shortly. Before I did this, I went to the range with the OEM springs and had no light strikes. Can’t wait to test it out, and keeping my fingers crossed.

Hey, how did you make out with the difference between 10 pound spring and 12 pound spring, I’m thinking about putting in the 12 pound since I don’t want any light strokes. Thanks in advance for your answer! Jimbo

I installed both springs after upgrading to the Mcarbo trigger and tested the trigger pulls on two gauges (Wheeler & Lyman).
My trigger pulls with the 12 and 10-lb springs were very close to the results in the How-To-Installation video. The 12-lb spring averaged 4.92 lbs, and 10-lb average 2.12 lbs.
I decided after installing the new mods from Mcarbo the Max could use a gentle massage with a Dremel buffing wheel and polishing compound to help speed up the break-in period on the new parts (Mcarbo sells the polishing kit).

Attached are a couple of “after” pics from the massage session.
Areas I worked on were the barrel feed ramp and areas surrounding the feed ramp, outside of the barrel that touched the inside of the slide, all parts showing wear after 1,000 rounds.
If I could see a mirror reflection on parts after polishing I knew that would be a good time to quit and enjoy the results of the smooth finish.
I could not remember seeing any vids or comments on polishing the inside ramps of the slide that touch the base of the barrel. This took about an extra 15 min and the results have exceeded my expectations.
I have had zero issues with the factory, or my reloads since doing the upgrades after just over 200 rounds.
I am installing new Ruger factory rear night sights next week and will have another 200 rounds fired to test against the upgrades.

I installed the lighter hammer spring, took it to the range, and it shot flawlessly. I don’t know if I’ll experiment and replace the hammer spring with the heavier one, as I’ve had no issues with the lighter hammer spring. It’s smooth as silk and there is enough trigger slack before the break so I didn’t have to worry about me firing any accidental discharges by using the lighter hammer spring. Just reiterating, I didn’t have any failure to fire issues, light strikes that caused the round not to fire, and I was using just standard Federal .380 rounds.

Yes Sir,
Thank you for responding, I changed all of the springs and used the 10lb instead of the 12lb. Once I realized I wound the trigger return spring the right direction, Everything worked great! I did only get a 2lb reduction on the trigger, but I like it!
