I want to lighten the trigger pull of my Shadow 2. The kit would replace the firing pin / spring, then reduce the hammer spring from 15# to 11.5#. Interested to hear if anyone has tried the kit and if it improved the SA trigger pull. If I run into light strikes I could up it to 13#. Feels like it's a good upgrade to try.

Just do it! You know you want to!
This is the gateway parts kit. :D After the easy install and noticeable improvement you’ll find yourself looking at hammers and reach reduction kits. In that moment when you are almost done with your first cup of coffee you’ll recall JoeL’s 200 yard handgun video and start dreaming… Yeah, I do need that stuff.
I run a couple of 75s with the 11# spring. The extended firing pin should overcome any hard primers.

Yup I ordered last night. I'm curious how it will impact the SA pull. I'll post before / after Lyman results.

Ultra lite kit and lotsa polishing is your best bank for the buck. Comp hammer would be the next best addition. By then you keep adding more, did that on my first sp01 tatical..eventually I had the pro package in… now I put the pro package in all my cz’s and get all the parts at once.

That kit will affect DA much more than SA. A comp hammer will net the most substantial improvement. A reduced power trigger return spring is worth another 1/2lb reduction in pull weight. Every CZ is different, but the last S2 I did required very little polishing.

Don’t have a Shadow 2 but doesn’t this come with upgraded hammer and trigger components? Doesn’t it come with a comp hammer installed?

Okay, I also got a reduced power trigger return spring and and upgraded trigger pin. I think that's all for now. The other upgrades might be a bit too tough for me to do on my own.
Are there any guides online about how / where / what to use for polishing?

Can’t speak to the shadow.
But Started out with just changing 75 omega pull weight by installing the omega series complete upgrade spring kit with extended firing pin.
Really reduced trigger pull. It’s 9 DA and 3.25 SA now. Previous was about 13 and ~7.
Still didn’t like the trigger travel and bit of mush when squeezing trigger so installed P series hammer with sear spring upgrades for that crisp trigger break.
Still 3.5 SA but absolutely no mush.
Nice crisp, clean break, and the trigger reset is only about 1/8” of movement.
And if I remember their website and what David told me correctly with anything under the 13# mainspring have to watch watch what primers and ammunition.
2 I was told are fairly “soft” think one was federals and would normally work with the lighter hammer spring but if want to use a variety of ammo, and it be a defense weapon go with the 13# main spring.

Cgw product description:
"Also included is our music wire 11.5# (HS-12000/black) hammer spring for use virtually all primer brands and types. Delivers an incredible DA in the lower 6# to upper 5# range."
I get all the parts on Monday. Won't be able to hit the range for a few weeks to test it out. I figure the longer firing pin is supposed to help prevent light strikes.

I think you’ll like it.
The longer pin is supposed to help with light strikes.
Are we looking at same website?
NOTE: HS-12000 is a competition spring and is not recommended for any self-defense application. HS-12000 is designed to be used with Federal and Winchester primers, other brands of primers may not run 100%. We suggest you thoroughly range test this spring with other primers to verify reliable ignition.”
The above is why I went with the 13# that came in the kit.
It boiled down to personal preference, and recommendation for defensive firearm to use for me.
We couldn’t be happier with the action and reduction in pull weight with parts we put in it.
Wife couldn’t even hardly get DA to break before putting the kit in it.
She likes it now b

I'm pulling the description from the ultra-lite kit page specifically for Shadow 2s. Either way, my Shadow 2 is a range toy so at worst if it's not reliable I'll just switch to the 13lb that came with the kit. I totally understand that for a defensive use-case you'd want to opt for the stronger spring.
I also wonder if primer technology someday will get better, or maybe already has. The only light strikes I've had in the last 3 years were some bulk Norma 223 when shooting my Ruger MPR.
I remember it happening more often when going to the range with my dad ~20 years ago.

11.5# and EXTENDED firing pin and reduced power FRS will ignite all primers I have tried.
13# and stock firing pin will ignite most primers.
8.5# and extended firing pin will ignite Federal and CCI (and maybe others) primers.
It all depends on the firing pin and firing pin return spring.

I got everything installed, SA is now around 2lb 2oz. I also did an SAO conversion. Is there any point to running a lighter hammer spring after a SAO conversion? I'm hearing some people say it reduces the SAO trigger pull a bit.
-
My experience with CZ DA/SA is that the main (hammer) spring has very little effect on the SA trigger pull. I see no reason why that would be any different for SAO. Try it for yourself, it is easy to change and you might like it.
