I removed the MCarbo parts from the Phantom and put them in a 75 SAO. Before installation of the parts, the factory SAO (with no mods or polishing) was averaging about a 4.5 pound trigger pull. After the install, the gun is averaging a bit less than 2.75 pounds, closer to 2.5 than 2.75 on the spring scale.

I think I'm going to go back to the factory mainspring. The SA force isn't what I like for the "pencil test". In a SAO Shadow I've tested a bunch of mainsprings and found no appreciable change in trigger pull weight, but the extra force with higher weight springs makes for more reliable ignition.

I'm not entirely sold on the kit for a SAO gun - if not using the mainspring. However for a DA/SA gun I think the kit is a great deal.

My only gripe is the rice grain slave pin. It sucks compared to the CGW slave pin.

Hopefully I'll have the kit today, but still waiting for some CGW parts too. While lightening the trigger pull is helpful, eventually, I think the most important will be the reach reduction kit, that trigger can be a stretch!

Probably waiting for a CGW floating trigger pin if nothing else, the MCARBO kit does not come with a replacement trigger pin, for $20 I wouldn’t expect it to.

Correct, and the starter punch and slave pin.

Seems like paying shipping twice would negate most of the savings.

With my two MCARBO CZ75b kits, I reused the factory trigger pin in one and used a CGW floating pin in the other.  I thought the second install would have destroyed the trigger pin because of the large flares it had, but that straightened out and looked really good after removal and most likely could have been reused. Anyway, the factory trigger pin I reused in the first install is holding up very well after 400rds so far with no lateral movement, and the CGW pin is working well too.

Also, I purchased a third kit with a 20% discount, only on 9-11, thinking I could install it in my Tristar C-100 or another 75b I was looking at.  I took my C-100 out today for the install and changed my mind since that handgun has a really decent factory trigger. I don't want a 3lb SA pull in a concealed carry handgun, just my preference.

Yea I don't really understand this kit either.

To work on the trigger you need a floating trigger pin because the flared pin from the factory should not be reused.

Sure you might be able to... But the floating pin is $6 or $7 that can be reused in the future. Working the trigger on these guns, my trigger pin comes out 10+ times. I would never consider reusing it.

If the cost of the floating pin breaks the bank then there are bigger problems than a slightly lighter trigger pull.

Having to buy springs from one place and then buying the floating trigger pin from another negates any significant cost savings.

I appreciate the experimental approach and attitude but it seems like a lot to go through for such minimal financial gains.

It would be like driving 20 miles away to get a deal, saving 2 bucks on your motor oil..but still having to buy your oil filter from your typical place.

Unless this is purely for educational purposes I just don't get it.

The question for some of us is this:
Why skimp on the springs with an unproven kit just to save a few bucks when you still have to buy the rest of the parts from CGW?

Such negativity in here over new products for the CZ 75. If someone bought the product and they're happy with the results, why try to convince them that they'd have been better off with a more expensive alternative at a higher cost? If you don't have anything good to say...

I remember when "the Angus hammer" was relatively "unproven" and when a guy from Louisiana began selling his "unproven" parts. MCarbo parts for the CZ may not have a lot of time behind them, but it's not MCarbo's first rodeo.

MCarbo is offering a handful of parts for $23 shipped. Do you know what $23 shipped gets me at CGW? A trigger pin, shipping, and $2 to spare.

Perhaps MCarbo will start selling a trigger pin, I know they're already looking at CZ triggers...

Anyhow, I'm happy with my $23 bag of MCarbo parts. I'm also happy with my CZ UB parts, CZC parts, CGW parts, and RCtech parts. The more offerings, the better.

IDK man seems to me it was just a question, not a negative statement? Seems like a lot of folks in this thread are overly sensitive of any perceived criticism, or questioning of the true value vs perceived savings in these kits. Earl asked a question, jokester might or might not answer it. IMHO either the MCARBO kit will sell and grow on its own merits or it won’t. I don’t know if the guys at MCARBO need all the cheerleaders they are getting in these threads, but I can say that the aggressive defense and personal attacks on anybody who doesn’t drink the MCARBO koolaid is starting to get seriously irritating.

This is a discussion forum.
I simply asked a question, as part of that discussion. Deal with it.

 FWIW, the Mcarbo kit isn't a "new" product. It's a low price alternative to an established product that another company developed. I really don't understand why a few people here are so defensive and apparently married to this product. It's pretty much guaranteed that any post in this thread that isn't a glowing recommendation, will be immediately followed by one or two people defending this product that they've only used for a couple weeks. Pardon me for being skeptical.
 I stated early on, that I see value in new/different products being developed for this platform. The APEX Tactical kits are a prime example, they offer something new. Still unproven, but they are innovative.
 This product is not that, it's just cheaper. In the end, that may prove to be a good thing, maybe not.
 My comments are sometimes intended to generate further conversation and provide documentation to assist new users in making decisions about products or modifications.
 Mixing cheap parts with Cajun or CZC parts is in my opinion false economy. I can call or message David, Scott, or Stuart just about anytime and get outstanding product support, virtually on demand. Their profitability directly impacts their willingness to provide that service to me at no extra cost. When profitability is driven from an industry,  innovation leaves with it.

I don't think negatively is the right word. None of us here are bashing MCARBO.

The appeal of this kit is price so it's totally appropriate to discuss the associated costs with modifying the trigger properly. Not doing so and touting only the cost benefit of the actual parts of this kit would be deceptive.

I do this because when I started with CZ's early in I had to learn a lot quickly and I paid more because I didn't have the right information.

Here ia what I learned:

1. Modifying these guns is expensive but the potential gains are incredible. When complete these guns are by far the best handguns I own.
2. Always use a floating trigger pin. You shouldn't reuse the flared pin
3. Buy a starter pin to remove the factory flare. Normal punches aren't as effective and you risk damaging parts.
4. Replace the firing pin retaining pin with a hardened one.
5. Use an O-ring to dry fire.

I'm sure there are more.

So let's discuss MCARBO specifically. I think it's great they offer parts. I don't think they understand the market. I think they offer a kit that is competitively priced yet overlook that other parts are necessary to complete the install. I suggest they make a floating trigger pin and offer a starter punch for sale with their kit.

This would be analogous to the discount motor oil example. Whoever sells discount motor oil should realize that at some point they should offer oil filters too... Because the two sort of go hand-in-hand and any cost saving on discount motor oil is negated by using multiple vendors and paying shipping etc.

For the consumer : I think it's the right thing to do to have these discussions and provide people with all the information needed to modify these guns.

When I started modifying my CZ's I didn't buy a starter punch and didn't buy a floating trigger pin. As soon as I sat down to disassemble the gun I struggled with the pin. I realized instantly that I couldn't use it again. Guess what. I had to go buy one and pay shipping costs a second time and wait a few days for it to arrive. I also picked up a starter punch. That cost me more money and more hassle. It was a learning experience.

You can call the mention of this "negativity" but my intention is really to inform others of what is really necessary when you make these changes.

The CGW floating trigger pin alone is $13 plus shipping.  Personally, I'm very happy how the MCARBO kit transformed my two 75's, it was an incredible change for my two handguns. I never thought that was possible for under $100+.  Correct me if I'm wrong, but does CGW or CZC even sell a lighter sear spring?

Oh, as of yesterday, there was 9 reviews at the MCARBO site for the CZ75 kit.
