  1. At local matches, they might not care - but to get a Shadow 2 to make weight there are a couple of things you can do:

    • Slide milling - I think Primary Machine used to sell a Carry Optics specific cut, which included more weight reduction than their Harbinger series.
    • Lok lightweight grips
    • Acetyl guide rod (if you can find one)

    The disco sets pre-travel. Without out it you're relying on a janky set screw that moves or change shapes. You can hand fit a CGW disco or buy a factory Pre B disco from CZC. I've done all three, the set screw is not optimal. 

    So with an SAO trigger and disco, you don’t need the pre-travel set screw? Only the over-travel?

    Would that depend on the SAO trigger style? There are several that have the release point farther forward (CZ SAO model) and some have the release point farther back (CGW flat).

    If you want to put race parts in you can but the SAO trigger will function better if you set up the race parts with a disco.

    How is that?  Even CGW recommends removing the disco.

  5. I bought the Armanov Handgun Recoil Spring Tester, and here is what I found:
    Installed Recoil Spring = 13.3#

    Longer Recoil Spring = 11#

    Shorter Recoil Spring = 10.8#

    In which book did you read such things?🙉

    Lighter slide = less reciprocating mass.

    Less mass = less spring force needed to slow/stop the rearward moving slide in recoil.

    Less mass = less spring force needed to close the forward moving slide.

    Most 2011s running 7 or 8 lb. recoil springs are Open guns.  Most 2011 slides are heavier than CZ slides.  The lighter the slide the heavier the recoil spring for the same PF, everything else being equal.

    Staccato XC, VooDoo Priest come stock with those recoil springs and are not Open guns.

     

    Everything I’ve read is the opposite:  the lighter the slide, the lighter the recoil spring (in general).

    Probably because 2011’s run much heavier mainspring, like #7, 19, 21. Most Shadows commonly run #11.5 to keep the DA pull weight down since their being used in DA/SA divisions.

    I thought there wasn't a correlation between the hammer spring and recoil spring weights.

     

    Doing a quick search - it looks like the CZ factory hammer spring is 20#.

     

    Are you saying a very light recoil spring (7-8#) is possible with a heavy hammer spring?

  9. Several 2011s can run a really light (7-8#) recoil spring, still cycle fast, feed reliably and return to POA.

    CZ Shadows running 130pf loads - most competitive shooters run an 11# recoil spring.

     

    How are the 2011s able to run reliably with such a light recoil spring?

    Slide weight? The 2011 design?

     

    Are CZ Shadows capable of reliably running a 7-8lb recoil spring?

    What modifications would that take?

     

  10. @kneelingatlas or anyone else:
    How would you polish to achieve a buttery smooth slide?

    Dremel?  If so, which attachments?
    Sandpaper?  If so, which levels of coarseness?

    Any other methods?
    Any places to polish besides: top of the frame, bottom of the slide and the rail groove?

  11. The internal parts of the S1 and S2 are the same and inter-changeable:  trigger, recoil spring, hammer spring, firing pin, hammer etc.

     

    The ergonomics are slightly different.

     

    Also, the SP01 Shadow makes weight in IDPA, the Shadow 2 does not.
