The new project has survived thus far!

 New SP-01 Shadow needs some love. These things do seem better in the trigger dept. than a bare bones 75, but are still heavy and creepy. I only ran 50 rounds through this gun prior to tearing it down.

It IS a big heavy lump of a gun. Shooting from a rest it almost felt like a .22, as it just absorbs recoil! My own range queen polished stainless is nice, but this is SUPURB! I can see why folks like them, but I just could not withstand the wait and added cost of the Shadow 2 at this point. I still love the P-09 but it just does not compare.

A few springs and polish, which I did take my time on, and an awesome SA trigger at 2.4 lb and a DA of 5.9 lb using the 11.5 mainspring and EFP, Yes!!!!!! I can do this!

I did have some problems that I had to work through, and I will get back later on that. For now, I just feel relieved the function ck is good and I am ready to go back to the range with it.

Nice.

I'd be interested in more details about the parts, work, pictures, too, if you have them.

I'm looking at the gap under the front sight.  Dawson lists dove tail depth of .060" for the 75 and a .085" for the 75 SP 01.  I wonder if you have a 75B front sight on your SP 01?  I don't think it will make any difference in function, just cosmetics.

Are you concerned about light strikes with the 11.5# hammer spring?

I've got a SP-01 Tactical that I put a CGW Pro Pkg and 10X bushing, Dawson F/O sights, my grips of choice, and polished internals all for $1100........literally I would put it up against the $1600 CZC Accu-Shadow and don't think there would be much/if any perceivable difference in performance........its so much less expensive to do the work yourself    Keep working it, your improvements will make a difference....

+1 except you listed it backwards.  The SP-01 and Shadow line of pistols have a front sight dovetail depth of .060 inch.  The standard 75 series have a dovetail depth of .085 inch.

It will affect your point of impact, essentially your front sight is .025 inch taller than the correct dovetail depth would be.  Not really an issue if your point of impact matches your point of aim but as said it looks a little funny.

Guys, I am not reallY sure about all or any of that. These are the Factory Shadow sights and do indeed have a small gap at the lower front, which bothers me not.

The FO light pipe IS a larger diameter than my CZC 1mm units, but it is quick to acquire nd everything is a tradeoff I suppose. I will not change for now, while I CONSIDER RED DOT OPTIONS!

Well Jimbo, you know this gun is not cheap if you can find one, and I am not made out of money, so I started out with a short parts list and kinda sorta wanting to play with this a bit.
So for just over a hundred bucks, CGW will rush out a ultralight kit with extended FP and lighter springs, a T1 disconnector that is pretty much already fitted for a short trigger take-up in SA mode and a single sided wing that can be massaged a bit if needed, a lightweight TRS, and a floating trigger pin.

As we all know, the best part of most all trigger jobs on a CZ is going to be a custom hammer. I own about three now in other guns and they are awesome, and yes I have become a trigger snob. Although the Shadow is supposed to come with an improved hammer, it is still kinda sorta creepy and sucky for us snobs. If I had to put numbers to it, based upon the sear height cut in the hammer it would read like this, which translates to creep and lost motion.

Average CZ pistol- .020
This Shadow- .015
This Shadow now after cutting the hammer hooks- .008. Oh, did I say that, well yes I did, and this stuff gets good!
CGW racehammer- not quite sure, but it seems even shorter at possibly .006 or .005 if I had to guess.

Polishing is a key element in massageing a CZ, and my camera will not do it justice.

Suffice to say the key surfaces look like chrome. My method is simple yet effective, and I am a lazy bastard to start with so I just use what works!

[Tok36]

Good stuff!

The people that call us "trigger snobs" are just unable to appreciate a nice trigger.

I bought a used Colt Series 70 once just because of the trigger.  My youngest son and I were walking through a gun show.  I saw a satin nickel Colt and pointed it out to him and told him how I'd always wanted a Combat Commander with that finish.  I asked for permission to pick it up and look at it.  I check it to make sure it was indeed unloaded and then asked if it was okay to dry fire it.  When I squeezed the trigger I didn't believe it.  I had to do it again, then one more time.  Then I was asking the guy for the paperwork to start filling out so I could bring it home.

I gave it to my youngest son (since I already had 2 or 3).  It's part of the reason he wasn't satisfied with his out of the box CZ 75 SA and why we've worked on it.

I'm not going to put a lot of time/money into some guns/triggers because they are "good" for me as bought.  However, some definitely need work/money spent on them or they just aren't fun to shoot.

Ha, funny you mention that. The new 70 series Gold Cup I traded for has a stock GC trigger. It is right at four pounds and quite good, with a tad of sear creep.

It is calling me to massage it just a bit! But I do kinda want to keep it original as well.

SO BACK TO THE SP-01 SHADOW!

I have massaged a few CZ's now but I do not claim to be an expert like some. I have tried hard to study up on problems and solutions as these guns can be a bit jikky on timing issues and such due primarily to manufacturing variances. Getting my head around what is doing what and effecting the other has taken me a few beers, and then some.

My initial feelings were that this gun may give me a challenge because the SA and DA breakpoints were very close and very far back in the trigger pull with little overtravel.  Well, sure enough, after installing the type 1 disco and cutting the hammer hooks, when the SA trigger broke the gun would fall to the disconnector and catch the hammer, thus requiring another pull to release the hammer in DA mode.

Ug, this sucks, it is the weekend, CGW is closed and David is not answering the phone, so put a few more beers down and waited until the next day. Yes I have an idea what needs to be done, I need to cut the lower edge of the wing on the disco so the DA is fully clear of the SA break and does not catch.

So as I initially measured the thickness of the wing on the CGW disco, it was like .113. After cutting the lower surface and fitting several times for function, it was .105, or reduced by eight thousandths.

The hammer arc is still good and slightly lower than the SA hooks now, which is as things should be, and I did not wreck the new disco having to buy a nother new one so it was a good day.

Another thing here, I have had this gun apart in fitting so many times now that I can do one in my sleep, in fact I still do!

So I called David on Tuesday and told him the story, asking if there was anything else I did wrong! He just laughed and said I must have done something right for a change!

Now that function test is good, I will try to take it out this weekend and run it in some.

Nice, I love it when a plan comes together.
