I've installed both CGW and MCarbo kits in my CZs.  They work equally as well in my experience. I've even mixed and matched the kits.  MCarbo instruction videos are great.  For me, the MCarbo kit is an inexpensive, easy start to improving CZ triggers.  It's not the end all but it's a great place to begin.  The trick to the trigger spring is not to bother with a slave pin but to use a needle nose pliers to install it and hold it in place while inserting actual pin.

I second the needle nose pliers for the trigger spring, much easier and faster.

I adjusted trigger bar spring and now the trigger resets nicely. Shot 300 rounds and noticed the single action was so light that I was setting some double shots by barely touching the trigger. Wondering if this is because of the reduced sear spring in the kit..should I tear apart and put the factory sear spring back? I put a cajun gunworks spring kit in my 75 it did not come with a sear spring and there is a slight wall in single action before the break. With the mcarbo kit no wall just a smooth hammer release

This is why CGW, doesn't sell a reduced power sear spring.

Took you long enough, Rmach. Gotta keep those royalty checks coming. [emoji1787]

What do you mean?

I did four Mcarbo kit installs on my 75s, and I installed the Mcarbo sear spring in three of them.  I wanted to see if there was that much difference with the factory sear spring in the fourth install, so I didn't put it in.  There's a slight heavier pull, but not enough for me to tear it apart and install the Mcarbo sear spring, so I left it out.  I wonder how light your trigger pull is? All four of mine are ~2.7-3.0 lbs in SA, and I never had any double shots with thousands of rounds fired.  I wouldn't want/like any chance for a double fire, so in your case, you should try the factory sear spring IMO.

now I don't feel so bad for chickening out on the sear spring when I installed my MCARBO kit in my decocker P-01.  I'm no trigger connoisseur, but the SA is just fine without it.

No offense Rmach, but that’s funny right there...

Seriously.  I ordered and installed CGW's .020" sear spring for my P-07 before I even installed their hammer, not because of hammer follow, but because the other mods and break-in had already made my SA scary light.  I needed to get my SA pull back over 3 lb to feel safe about it.

I haven't worked with any MCarbo kits, but I did watch their installation video, like I watch all full disassembly videos of P-07's or P-09's I can find on YouTube.  When I saw that they were installing a reduced power sear spring, I was like... what?  I wouldn't be against trying one of their kits in the future, but reduced power sear spring is definitely one of those parts I would be leaving out.

Removed mcarbo sear spring and all is good again! Don’t recommend installing that part as it will make your trigger unsafe!

That's good that you found the right combination for your particular CZ.  I think you are the only one that experienced a double fire that I read about with this kit.

I added the M Carbo kit to my brand new and unfired 75 Compact.

Before:
DA = 10#-14 oz
SA= 4#-7 oz


After:
DA= 7# 6 oz
SA= 2#-11 oz
