These work great I have them in both my P238 and 938 legion trigger pull is dramatically reduced hammer is much smoother and the rest is far better with the kits

I love it

I bought the Gen 1 trigger kit and a polishing kit. I installed the trigger kit and polished the hammer and feed ramp. I don't have a trigger pull gage, but I can say that my P938 trigger is much better. The improvement to the shoot ability of the pistol is significant. Bonus, it was really easy to install.


Disappointed in the reduction of pull

I ordered a Gen1 trigger spring kit based upon the claim that it would reduce my factory trigger pull by close to half of what it originally was. I received the shipment very quickly and was impressed with that, however that was probably the only impressive thing that happened. I have a digital trigger scale and decided to do a before and after comparison of the replacement. My five pull average before the trigger spring replacement was 7# 13.2oz. I then replaced the springs that come in the kit and did another five pull average. Surprisingly the pull was only reduced by about a pound with my after replacement five pull average being 6# 12.1 oz.
I reached out to the company about my results and their solution was that I may need to do additional trigger work in order to actually achieve the results they advertised. Considering they advertise a certain range of trigger pull reduction I expected my trigger to be closer to those numbers with no additional work.
Disappointed overall with the result and the companies solution. I try to support small business owners and especially Veteran owned firearm component companies, but this was definitely a miss.


Another great product

This is the third spring kit I’ve purchased and installed from Mcarbo. This one on my wife’s P238 turned out just as good as my 2 guns. Great product and easy to install. Videos are priceless.


The comfort of firing my pistol is amazing! The confidence of American made product is exponential with Mcarbo and a Crusader trigger.

As of 4/20/21, we do not have an ETA on the Sear Spring for this kit. The Gen 1 Kit contains the same Hammer Spring and Firing Pin Spring and can still be used in the Gen 2 models. The Sear Spring is a very sensitive design and we are working on releasing a better, updated version! If you'd like to be added to our product wait list for either the Gen 2 Spring Kit, or just the sear spring itself, please shoot an email over to, and we'll get you added! April 20, 2021 9:59 AM
