Just got my SP-01 tactical yesterday, o man does it ever have creep, even with the single action, the "hook" on the hammer is waaaaayyyy too big, does anyone know how to take it apart? And what else do you have to do beside file down the hook on the hammer?

send it to Armco or Dark Int. for a proper trigger job. If you plan to use it for IPSC production then all u can do is polish the parts..
 
I got it from Armco, Gunnar's assistant is sick, he's doing everything himself, busy as hell. He's still making the FO sights for the SP-01 a trigger job will take much longer. He told me just to file down the "hook" on the hammer, but it's the taking it apart part, that's a bit problematic. And I like keep my guns close by. Sending it away isn't an option for me, at least for now.
 
Hmmm,

No, I didn't say to take it apart and file down the hammer hook! Basically, no CZ is "beginner-friendly", and what the conversation consisted of was how to replace the mainspring with a softer CZ one. Also some discussion of how I would get the hammer out if needed, but with no expectation that someone would do it, and FILE it... :)

I do NOT use a file in any way when doing trigger jobs, and I know Rodger (at Dark) wouldn't either!

One thing about the decocker Model CZ's is that there is only one hammer hook actually used for single action let-off, so THEORETICALLY you could get a lighter trigger pull with the same spring pressure. Remains to be seen. Haven't really gone to town on on of them yet, but it's a foregone conclusion I will. Meanwhile I'm off to the sunny south tomorrow AM for a Todd Jarrett course. Looking forward to it :)

PS - the SP01 sure does shoot sweet! Had it out on sunday and the muzzle jump - with the same ammo- is WAY less than my LDA Para, and my para, a large all steel 1911 double-stack gun, shoots plenty soft. Would I switch? Maybe... Sure do like the LDA trigger pull, though!
 
Sorry Gunnar, I guess I misunderstood you. Thanks Musky Hunter, I will do some polishing as soon as I take the gun apart, after hours of looking at the parts diagram, and tons of reading on different cz forums. I'm am confident enough to say that I understood how the whole action/trigger assembly works now, and I'm also determined to take the SP-01 apart even if that meant having all the springs embeded in my carpet. I will just see it as a learning experience.

And now for those of you who would also like to know how to take the SP-01 Tactical apart, here's some instructions I found on the CZshooter.com forum

Hi all who are interesting in

This is for those who are interesting in disassembly and assembly CZ with Decocking system. I did it on my SP-01 Tactical.

Pls. I am not gunsmith (guns enthusiast only) and English is not my native language. For this, forgive me for some inadequacies.

Disassambly

1 you have to take off slide. On the left side of gun, you can see springs (first from left insure decocking lever against move from side to side. End of this spring must be lift up to be able to protrude decocking lever.

2. You have to dismantle ejector (container with internal parts. For this, you have to use helper pin 1. This pin must be little less in diameter then is opening on the left site of frame and lengths must be exactly the some like width of container (18 mm) ID 2,7 mm) . This pin help you to replaced original pin (from right to the left) and removed ejector (container) with all internal parts together ( firing pin block lever with tiny spring, sear two springs – sear spring, decoking lever spring and decoking lever). REMEMBER original pin keeping the container (ejector) in frame is conical and on the left side is narrower and for this must be removed from right side to the left and installed back from right to left side. (For orientation, you can see on original pin signs narrower side of pin is signed 1 black circle and on the wider side of pin you can see two black circles. Always install this pin from the left side. {Just found this out, you have to drive the pin from the right side, so that the pin comes out from the left side of the frame. When reassemble, just insert the pin from left side.}

3. If you want to disassembly ejector-container, you can remove pin only. However, be very carefully springs flies well.
Now you have trigger system dismantled. I do not want to describe hammer dismantling because it is normal easy operation described on this forum and I hope normally skilled man or woman would be able to do it without any damage to the gun and themselves

Assembly

Now this is real pain to get everything together.

1 In this step you have to use helper pin 2 (12 mm long), which is the some lengths like width of sear. I am using it to assembly springs (two springs) into sear. Both springs are positioned in sear. First what I install is sear spring and second is decocking lever spring. Right orientation of springs is visible in manual If you see internal surface of ejector- container you can see two notches. Legs of the springs must be hold in those notches. If you have springs and sear together you have to put the sear with assembled springs into ejector. I did it from bottom part of the ejector-container. Now you have to replace helper pin 2 for longer helper pin 1 so sear with spring are hold in ejector container in right position.

2 Now you have ejector with sear and spring assembled. Now you have to install decocking lever, firing block lever with lever spring in ejector. For this you have to slightly shift a pin from side to side to be able to install firing block lever on right side of ejector and decocking lever on the left side (both parts are in ejector container). Last operation to complete ejector assembly is to hook bottom leg of the decocking lever spring for bottom leg of decocking lever. You can test this and when decocking lever is operable and spring returns lever back, everything is OK. Now you can assembly ejector into frame. For right position of ejector, hammer must be fully forward. Now you have to replace helper pin 1 with original pin from right to the left.

3 My tip. To install decocking lever with DL spring I had used small drop of glue to spring was hold in right position on decocking lever and I was able to install them..


I hope in the future I will repeat disassembly and I would use my digi to get a pictures.

First I am not a gunsmith and there is description of my way how I did it. Second apologigize me for English it is not my native language.

He wasn't a pro gunsmith, if he can do it, I can do it.
