MCARBO CZ 75b trigger spring kit review.

[Rmach]

New update with Wheeler digital trigger pull readings.  I can only give the readings after the kits were installed since I did not have this Wheeler gauge prior to Mcarbo kit installations. All readings are an average of 10 pulls.

2016 standard full size CZ75b SA 2#13.2oz  DA 6#12.2oz (about 3,000 rounds fired)
2018 polished stainless 75b    SA 3#0.00oz.  DA 6#13.8oz
2019 polished stainless 75b    SA 2#15.6oz   DA 7#1.7oz
2019 polished stainless 75b    SA 3# 5.6oz    DA 7#7.0oz  (this one has the factory sear spring)

If there wasn't a bit of hammer cam, these numbers compare very favorably with my Shadow 2 and Shadow 2 Orange, despite what Earl thinks...
stock Shadow 2............ SA 3#2.5oz DA 8#13.2oz
stock Shadow 2 Orange SA 2#13.7oz DA 8#7.4oz

I do have a new CZ75b retro that is factory stock and the SA was 4#11.7oz and DA 9#6.8oz.

Ran at least another thousand rounds through my Mcarbo 75s since the last post, and all of them are still performing better than ever.

Thanks for the updates, I just installed the MCARBO kit I don't have a trigger gauge but I do feel the trigger being smoother  I haven't shot it yet but I'm expecting my groups to be at least a tiny bit tighter

Eight months after the last post, and this Mcarbo 75 spring kit still has outstanding reviews with no failures.  All five of my kit installs have had no problems to date.  I have NO affiliation with this company other than using the product.

After reading the 95% positive reviews and watching what may be the best installation video of CZ parts (or any other firearm product) from Mcarbo, I ordered the spring kit with a new trigger pin, and a stainless steel guide rod.

The video is detailed and inspires confidence in both the product and installation.

Glad to have found this topic here with real people reviews, not merely shills.

Couple thousand rounds with the McCarbo spring kit, and guide rod. No problems.

Another 5 months has passed with no problems or part failures with my five installs.  I'm sorry, but I just have to post this because several experts on the forum had absolutely nothing good to say about this kit when it first came out, especially with the new sear spring.  I'll still say today, this kit was the best money I ever spent on my 75s. There are close to 500 very positive reviews posted at the Mcarbo site on this product.  I HAVE NO AFFILIATION WITH THIS COMPANY, other than using the product.

As long as you are happy with the parts that's all that matters. I buy parts from places that I like and I'm happy with my results and could not care less what anyone else thinks.

I've installed three M*CARBO CZ trigger spring kits on my 75b, P-01 Omega, and 97b with a 30% average reduction in DA and SA pull. While installing, I did slight removal of machining marks and polishing on certain parts. No sear and hammer angles were altered. All are very smooth now in addition to the reduced trigger pull.

The installation videos are exceptional and make the process relatively easy though it will still take much longer than you might first think. You need a few additional basic tools like alignment pins, picks, and good bright lighting, along with patience.

You could send your gun out to different places to have this done for much more money and a long waiting period, but if you're willing to learn and take your time this is a pleasant way to spend an evening or two and learn how your CZ works.

Waiting for their next sale/coupon code, missed out on the last one.

Someone I know has a matte stainless 75B to outfit.

One year later and the MCARBO Kit has performed flawlessly. I will post another update once I break down the guns and report how the parts look and with data on number of trigger pulls.
