D.I.Y. Trigger Job on my SP-01!
« on: December 03, 2011, 07:26:55 PM »
I read through this post about doing a trigger job on an SP-01 in the CZ related Frequently Asked Questions, Gunsmithing/Maintenance section so I decided to give it a try:
http://www.czfirearms.us/index.php?topic=14688.0

It was not such a bad experience for me. I got the sear cage out of the frame without much trouble. Then I put the sear cage in a plastic bag and punched through with a pin drift to remove the sear pin and it's little parts & springs. The Firing pin block lever spring is a amusing little thing to work with. Thankfully the plastic bag kept it from flying away. I also forgot to remove the hammer spring before removing the sear cage but the CZ pistol was rather forgiving of that blunder.

I did not really do much after it was apart other than true up the sear tip and hammer notch with a knife sharpening stone. I also lightly polished the surfaces on the bottom of the sear cage that bear on the trigger bar. The intention was to remove any burrs, not change angles

Reassembly was not all that bad except I pulled some more of my hair out with the tiny little Firing pin block lever spring. It did go back in place eventually, but it was certainly a bad hair day and a work out for the tweezers.

After I got it back together, the single and double action pulls seemed much improved and smoother. I did not weigh the single action pull before my work, but after reassembly it weighed in at about 4 1/4 pounds.

The CZ related Frequently Asked Questions, Gunsmithing/Maintenance section is a big help for do-it-yourselfers

Thank you for providing the valuable info  ;D

Congratulations.  It's a good feeling to get it back together and SEE that it's much improved!
It is now "your" pistol. ;)

I've done both a standard and a decocker models using the info on this forum.  I think I can easily reassembled 2 or 3 Standard models in the same time it takes for me to reassembled a Decocker. Getting the extra lever and spring back into a decocker sear cage just so with a slave pin is where the extra time gets spent.

Now that Cajun Gun Works offers a decocker hammer with hooks cut "just so", I've been thinking of opening up my SP01 Tactical again.  Just takes money and time...

Quick Clarification I need; Can there be a safety and decocker on a sp-01... for instance can i transform my standard sp-01 into a shadow style safety that decocks?

It's definitely satisfying.  I mirrored-up my internals a few weeks ago.  The friction points were already pretty smooth before I started, whether by the Shadow Line being polished before being sold or by the thousands of rounds I've fired plus who knows how much dry firing, I'm not sure, but it's still better now than it was.  When I was done, I had the immediate desire to buy another pistol and start the process again.  That desire has not subsided. ;)

You cannot transform an SP-01 manual safety to a decocker and I don't think there is a Shadow style safety that will double as a decocker. The P-09, P-07 or the 75b Omega can be switch between manual and decocker controls.

Does any one know if i can turn an ambi Decocker into a left side only. The right side messes with my index finger when decocking.

I'd say it can likely be done but would require a custom part to replace the right side lever. Or maybe you could cut down the existing lever. Mine is a ambi safety model so I don't have direct experience.

Someone said a CZ 75D part would work. Apparently, that is a left side only decker. The right side is just more in the way imho

You got me motivated to do mine.
I just did this over the past couple days with my phantom.  had some frustrating moments like losing a spring for a little while in the carpet, the wife getting mad at me because i was "ignoring her", and every tutorial being based on a model different from the phantom.  But I have it down now.  The hardest part for me is actually trying to get the spring set with the trigger pin. lol. the sear cage and all that ended up not being bad... except for temporarily losing the smallest spring.
It took the grittiness out of the da trigger. 
What springs would improve this any more?  im not interested in lightening the trigger
