Spo-1 tactical pro package

[ttrashman1]

Has anyone had any problems doing there own upgrade? If so what problems did you have? I getting ready to order my pro package and want to get a idea of the problem spots ahead of time.

I recently installed one in my 97 BD, pretty much identical internally.  Only thing that gave me problems was the firing pin block lifter spring, it went walkabout in my shop without me even noticing it was gone until I started putting it back together.  Luckily I found it, but I'd recommend having a spare or two on hand.  Other than that, a slave pin is pretty much required putting the sear assembly back together, but I found what worked better for me was assembling the sear with the regular pin, thin pushing it out with the slave pin to reinstall it in the pistol.  Finally, I'm a huge fan of the CZ Armorers manual for these guns, having lots of clear pics and a step by step guide really makes things much simpler.  Lots of other good info in there as well.  Good luck.

   Starter Punch for starting out the factory trigger pin and in some cases starting out the staked sear cage pin in the steel framed pistols. Extra FPB lifter springs for insurance, they have a tendency to get lost or damaged. A sear cage slave pin is a helpful tool to have unless you want to make one. Removing the factory sear cage pin can be a bit touchy the first time around because it not only retains all of the sear cage parts into the sear cage but also holds the sear cage into the pistols frame. A slave pin not only makes reassembling the sear cage easier but also makes removing it intact with all of its parts retained possible. If it can be removed intact you will have the opportunity to examine it be fore you take it apart. You can even take reference pictures of the assembled sear cage to aid you in reassembly if you like.

   Read/watch the available video and forum guides for CZ75 variant decockers, then read/watch them again. Do not plan on shooting your upgraded pistol the next day or in the worst cases next week if parts need to be ordered. While things may go smoothly this is not guaranteed. I have personally experienced and seen many other forum members get into trouble due to rushing the process the first time around. If something is not going right, rather than forcing it, stop and ask questions. After the first go much of the potential mystery in the process fades away.

   Reviewing/watching the published available knowledge, assembling the right tools and taking your time can make the process more successful and enjoyable. My intent is not to suggest that the process is really hard but it can be harder than it needs to be depending on how you approach it.

I really think doing it the first time on your own is the worst part after that its not bad at all ,, ive got my 75 compact tore apart for a polish job and waiting on parts and i was so nervous taking it apart but now its no big deal just go slow and take pics if needed ,,  i have no doubt you can do it ....

Did my own SP-01 Tactical decocker upgrade.  Removing the factory staked hammer pins is a major PITA.  Broke a punch but got it done.

I cheated the factory lifter off the end of the sear cage slave pin without losing anything else; be super careful and you can get the new one on without trouble.  BUT be prepared if something slips.  You MUST use a slave pin !!

IMHO worth it to just order a new hammer strut and forget the factory hammer disassembly entirely.

Also wiggling off the right side decocker lever was a PITA - maybe there is a knack but the tiny catch lever was hard to manipulate.

Disclaimer - I have extensive experience on revolvers, 1911s, Sigs etc etc.  Even S&W models 41 and 52.   The CZ decocker is not an easy job but manageable if you use the online tutorial and go slow and careful.  Take lots of pix before each disassembly step.

Hint:  tweak the mag release spring leg and replace the magazine release if desired while you have the disconnector and other guts out anyway.  I missed this.

I did a polish job and installed the basic pro package without any issues at all.  So far, my tactical is the only CZ I've ever had apart.  I DID watch a video that detailed the disassembly and reassembly process though.  That helped a bunch! I used one of the other pins for the slave pin.  My only recommendation when it comes to stuff like this is to go and get a big gallon size clear baggy, and work inside it when removing stuff.  Not losing little springs is a huge time saver! LOL

Great idea - get 2 gal ziplocks at Wal-Mart.  Lots more room.  I have launched detent balls, plunger springs, 'e' and 'c' clips, you name it.  Hours of moving junk in shop to scour every nook and cranny, then reorder $0.99 part and wait days.  Find things months and years later,  some I can even ID.

If you do have to install a FPB lifter spring, here?s a suggestion that may help.  I take a plastic drinking straw and make a vertical incision down the middle, about an inch long, on one end.  Then, at the base of the incision, make a horizontal cut removing one half and leaving the other half intact.  Now, with a small piece of scotch tape, lightly wrap the remaining half of the straw.  When installing the lifter spring, place each leg of the spring inside the mini tube created with the half-straw and tape ? just far enough to hold it securely.  This technique allowed me to more easily place the spring in the proper position during installation.  Trying to do this with just my fingers was an exercise in frustration.  Hope this is useful.

Thank you for all the great advice. Can always rely on this forum!!!

A small spot of grease on the end of the FPB spring works wonders too. Put the grease on, affix to the FPB and put it back in.
