Trigger spring kits
These are awesome spring kits. I installed a set on my CZ Shadow 2, my CZ 75 P01 Omega, and now my CZ Shadow 2 compact. They made a good trigger even better.
Smooth and effortless
I replaced the springs on my CZ Shadow 2 with the kit parts and polished the trigger bar and main spring strut with 1000 grit. The factory Shadow 2 trigger pull is decent but after the trigger upgrade and polishing the DA is effortless and the SA is less than 2lbs. It's crazy smooth! A definite must if you want the best trigger pull available.
great products
I put one of these spring kits in a new shadow 2 compact that had a good factory trigger. This kit brought it to the 2 3/4 lb ,what I prefer in some of my CZs that have the $275 upgrade kit. Great low cost improvement with excellent videos showing installation.
CZ Shadow 2 Trigger Upgrade
Since I have decided that my CZ Shadow 2 is my favorite handgun, I ordered the trigger upgrades that come in the Shadow 2 kit, to include the floating trigger pin.
Viewed Chris’s excellent video, based on the CZ 75, then went at it. When I was through, the trigger pulls were just over 50% reduced, with a smooth, quick and light 2 lb. 4 oz. single action pull. This is such a great value, and makes this gun exponentially better. I’m just getting started with this gun, and I’m glad I began the journey here, with a simple spring kit. Sky’s the limit now. You must get this kit if you love your CZ.

Highly Recommended!
I was quite impressed with M*Carbo spring kit; the kit helped reduced my SA pull from 4# down to around 1.6#. You video was easy to follow and helped tremendously with my installation. Highly recommended!
Perfection
It took a perfect shooting pistol and made it even better. I didn't think it was possible to make a shadow 2 better, but it did. I will be ordering 1 for my p01.

Do you have anything that does fit the Compact or Carry?
Does this work on the Shadow 2 Carry?
My apologies, I just saw the info that says it doesn’t fit the compacts.

I ordered this and installed all parts on my Shadow 2 Carry. However the sear spring looks like a completely different part. What can I do here?

No, the M*CARBO CZ Shadow 1 & Shadow 2 Trigger Spring Kit is not officially confirmed to work with the Shadow 2 Compact. Why Compatibility Is Uncertain: 🔹 Platform Similarity, But Not Identical - The Shadow 2 Compact uses a revised fire control system, frame profile, and possibly shortened sear cage components compared to the full-size Shadow 2.
How about the Shadow 2 compact?
Yes, it will work on the Shadow 2 Compact and the Optics Ready (full size) and it works very well on both guns

Would this work for a Tactical Sports 2 - TS2?
No, the M*CARBO CZ Shadow 1 & Shadow 2 Trigger Spring Kit is not compatible with the CZ TS 2. The CZ TS 2 uses a competition-style single-action-only (SAO) trigger, which is fundamentally different from the DA/SA system used by the CZ Shadow 1 and Shadow 2
By CZ SHADOW 1 do you mean CZ 75 SP-01 SHADOW?
The first generation was called the CZ SP-01 Shadow, the new generations are now Shadow 2. The 75 series is a separate series. The actual CZ 75 SP-01 Shadow is just a variant on the 75 itself. If you are getting the CZ 75 SP-01 Shadow you will need to go to the 75 series spring kit and not this one.
By CZ SHADOW 1 do you mean CZ 75 SP-01 SHADOW?
Will this kit work w/CZ TSO?
We have not tried it in that model as of yet. I can not say if it will or not.
Does the CZ 75 floating trigger pin option only work for that model? I have a Shadow 2 will I need to change that out to get a better feeling trigger?
The floating trigger pin is also compatible with the Shadow models, and we do recommend including the pin if you have not already. Just be sure to select "YES" in the drop-down to include this pin with your spring kit purchase!
This spring kit works for cz shadow 2 SAO ?
Hi, we have not tested this here at our facility, however, our gunsmith believes the kit should fit and function fine. We are not 100% certain if the firing pin spring is a different size from that of the Shadow 2 SA/DA. If so, you may want to keep using the factory firing pin spring and hammer spring.
