Critical Look at the Shadow 2

[Chilidip]

Bit of a question that runs off on a bit of a tangent (apologies iff too far off) does anyone know if a shadow 2 will be compatible with a kadet conversion kit?

With my countries restrictions, it would be advantageous if it is, but ill still probably get one if it isnt.

Thanks for your time

Not compatible.

Some thoughts from europe here on the shadow2
First shots with the 2 and i was surprises how bad the trigger was,a lot of sa creep and a lot of pre travel like Smeky said,
It was verry hard for the owner to make good groups, while he is a good shooter with the shadow 1..
Both in stock configuration.

After shooting my SA shadow 1 ,he was surprised about the trigger,
Talked him in to get his shadow 2 in SA....
After some trigger hooks work and some spring changes....wow the trigger is now crisp and clean.
SA less pre travel,good reset, no creep.
Feels better than my shadow1 now, both with the stock hammer.

Feels almost like the ts orange, with a pound more .....almost, lol

Does this mean that the S-2 uses a standard 13# recoil spring? Just trying to plan ahead for parts....

I suspected as much. Cheers.

As promised, here is a list of some dimensions of the internal parts, what is common across the spectrum and will cross reference:

S-2 hammer spring wire OD = .042" which equates to a 14 - 14.5 lb. hammer spring
S-2 recoil spring wire OD = .042" which equates to 13#'s
Firing pin spring wire OD - .029" which equates to OEM
Firing pin length = .2.468" which equates to OEM
S-2 Disco down leg center thickness dimension is .125"

This is a comparison of hammer hook heights, from the sear bed to the top of the hammer hooks:

S-2 = .028"
CZC = .025"
CGW = .016"

Everything in the frame is standard CZ Shadow as follows:
Grips
Sear, sear spring, sear pin & cage
Trigger, trigger pin & trigger return spring
Hammer, pivot pin, retaining peg, disco & strut
Safety detent & spring

What's different:
Manual safety is like the Tactical Sport & SP-01 Compact
Manual safety is unique to the S-2 and is the same as the SP-01 Compact

We'll get more info to the forum in the next few days.

David thanks for your work. I just picked mine up yesterday and it looks like I will be placing yet another order!

Think its use  a heavier one, 16 or 18, it ejects the cases far away.

I would start with an 13 and try an 11 later, use the plastic buffers.

Try to lichten up the trigger with a 13 mainspring and new firing pin spring

Thanks. I'm just wondering if it uses the same springs as the full size 75/SP01? I didn't know if the S2 uses a new type of spring that isn't available yet for purchase. I run 130ish PF ammo which is fairly light.

Recoil springs and hammer springs are the same for the "old" Shadow vs the S-2.

Thanks David! Sounds like I'll need to order some springs...

We have dissected the slide and here is what we have observed:

Rear sight -  exact same cut as the Shadow 1.  So any sight that fits the original Shadow will also fit the S-2
Front sight - exact same dovetail depth as the Shadow 1.  Sights total height is 7.5 mm or .300"

Firing pin is the standard Shadow 1, measuring 2.468" which means the CZC or CGW extended firing pins will fit and work

Barrel total length -  4.670" or 118 mm, which is longer than the Shadow 1
Barrel OD -  exactly the same as the Shadow 1, which is .550"
Barrel bushing - the same one used in all SP-01's, which means the CZC Accu-bushing can be used or the CGW 10X bushing


Extractor, extractor pin, and extractor spring carry over from the Shadow 1.

Slide appears to utilize the same manufacturing method as the P-07/09, which is an extrusion.  Minimal machining is required with extruded parts.  We have noted the slide hardness is greater with the P-07/09 slides, and this is reflected in the S-2 as well.

The S-2 slide appears to use more modern manufacturing techniques, which equates to better QA/QC and reduced tolerances compared the "classic" 75 line.  Overall the S-2 is big leap for CZ-UB, a welcome observation. 

We would assume the classic line would get updated manufacturing in the future.  Would be nice to see the same quality we are seeing in the P-07/09 and S-2.

Great news! Glad to hear they have stepped up QA/QC.

This is going to be one hell of a pistol once it gets the Cajun treatment. Can't. Friggen. Wait.

David:

How long before CGW comes up with an upgrade plan for the S2, and how soon can we send ours to get Cajunized?

[WxGuy]

I'm going to wait until all the upgrade packages are finalized before I order a S-2 from CGW.  I have patience (I think!).

My plan also. The triggers aren't spectacular out of the box so I want it cajunized first. 

[andrew1220]

Sooo is that Shadow 2 you have bought/spoken for already?....If not, I call dibs on it! 😂
