CZ-82 Gunsmithing Part 4

This will be my last post before leaving tomorrow morning. The next time you hear from me should be from the Bustling Metropolis of Louisville KY while attending the NRA convention and the Second Amendment Blog Bash.

In the first post of the series, we Introduced the CZ-82 to our collection and identified the areas that needed work.
In CZ-82 Gunsmithing Part 1, we discussed the loose grips issue and disassembled the slide components.
In CZ-82 Gunsmithing Part 2, we disassembled the magazine catch and lightened the magazine catch spring tension.
In CZ-82 Gunsmithing Part 3, we removed and disassembled the safety and disassembled the slide.

In this edition of CZ-82 Gunsmithing, we’re going to remove the slide stop and spring, and then the trigger, trigger spring and trigger bar.

As always, we’re picking up where we left off last time with a partially disassembled CZ-82 so if you are starting with a complete pistol, make sure your pistol is unloaded, then start from the beginning to get to this point.

The slide stop is very easy to remove in and of itself, however it also incorporates a wire spring that engages on the trigger guard latch pin.

The spring catches in a lip in the trigger guard latch pin (at the arrow).

The first step in removing the slide stop is to push the pin spring out of the lip so that it is no longer engaged in the pin.

Then drive out the trigger guard latch pin with a pin punch.

Note that one end of the pin is machined to a smaller size than the main part of the pin. This means that the hole on the right side of the frame is smaller than that on the left and that the pin can only come out from right to left (it actually appears to be from left to right in this picture because it is looking up from the bottom. When I say “from right to left” I’m always referencing it from the pistol upright and the barrel facing away from you).

The wire spring is then pulled out of the hole in the slide stop and the slide stop pulls easily from the frame.


Next is the trigger, trigger spring and trigger bar.

They are not difficult to remove either, but are a bit trickier to reinstall so pay close attention to how they are oriented when taking them apart.

First, use a pin punch to drive out the trigger pin. This one was not tight at all and may not even require a punch to get out.

Once that pin is removed, you can lower the trigger and fold it back out of the way to get a good look at the trigger spring.

It is a coil spring that the trigger bar pin passes through and provides tension between the trigger and the trigger bar.

As you can (hopefully see) there are holes in both the trigger and the trigger bar for it to pass through when installed.

After you’ve gotten a good feel for the orientation for the spring (or have taken pictures for future reference as I did), remove the trigger bar pin.

This pin is also a loose fit and may just fall out on you. When assembled, it is up inside the frame which is what keeps it from falling out under operating conditions.

Once the trigger and trigger bar are separated, they can be pulled free of the frame. You may have to do a little maneuvering to find the right angle to get the trigger bar out, but it shouldn’t be too difficult.

One more shot of how the trigger, trigger bar and trigger spring go together. It may be easier to see without the frame in the way.

That’s it.

In the next exciting edition of CZ-82 Gunsmithing, we’ll remove the mainspring and then the hammer strut, hammer, sear, disconnector and associated other small bits and pieces which will complete the disassembly posts.

Next Post in the series.

  1. Excellent instructions, great pictures! One thing: You say, “The first step in removing the slide stop is to push the pin out of the lip so that it is no longer engaged in the pin.” Shouldn’t that be “push the SPRING out of the lip…”?

  2. On my 89 and 90 there is a roll pin instead of the trigger guard latch pin ass you show. The pin spring tends to slip and interfere with the trigger guard from time to time. BTW thanks for this great posting.

  3. Yes, on one of mine, the trigger guard latch pin is a roll pin. It's important to have the roll pin installed so that the gap doesn't interfere with the locking of the trigger guard. Basically, you want the trigger guard to engage with the round part of the pin, not the gap.

    Otherwise, it works pretty much the same.

  4. I have a CZ-83. Recently the hammer has been following the slide forward and stops on the half cock notch. Also in pulling the trigger double action, sometimes the hammer catches and starts back but falls back onto the half cock notch?

  5. Troubleshooting for this can get pretty involved. My first guess would be that the sear spring has either slipped out of place, or is broken.

    Check this post for information on the sear spring, auto safety and ejector and how they go together. That section starts with the 9th picture on the page.

    If that doesn't help you figure it out, shoot me an e-mail (link in the sidebar) and we can talk in more depth.

  6. Thank you for your excellent pages. I found them after I encountered a problem with magazine release on my beloved handgun, and neither a friend gunsmith or gun shop professionals were able to help.
    I have compounded my problems when, during exploratory disassembly, I managed to dislodge the slide stop wire spring.
    Following your detailed directions I was able to purchase replacement parts from CZ, fix the problem and put everything back.
    My CZ (Czech made) had one detail different from your directions – the trigger guard latch pin was actually a spring pin (a quick fix by previous owner?).
    Now I have my favorite handgun back in reliable working order and I am thinking I should give it some good wooden grips for good looks.

  7. I have 2 CZ 82’s and have noticed the trigger guard latch is not the same on each weapon. One us as you show ( machined to a smaller size on one end ) while my other CZ latch is the same diameter on both ends. Also, the same size diameter pin does not have a channel cut in it to secure the slide stop spring. Is one if my CZ’s an upgraded model?

    • Yes, the there are a couple of different versions…some of the newer models just used a simple roll pin rather than the machined pin with the slot. Installation is basically the same, but there’s no slot to worry about and the roll pin can go in from either side.

  9. I know I am probably reading this many moons after it was written but did you ever write the instructions for reassembly? I have my CZ82 in pieces and need to reassemble it. I have more than a basic knowledge of guns but this CZ is not as simple as a Browning or Glock. I would appreciate any instructions as to reassembly.



  10. Great series.
    I have a CZ 82 and a FEG PA63. The CZ’s double action trigger is much better than the FEG’s, but the 82 has developed a trigger glitch; when I pull the trigger, it doesn’t return fully to the original position.

  11. I have CZ 82 where the slide stop spring fell out when I first took the slide off the frame. The spring was L-shaped…no hook at all. Was there ever a variation that used this type of slide stop spring, or should I not bother with it and get one with the hook?

    Very helpful blog by the way!

  12. Hi I just recently purchased a CZ82 as a gunsmith special. The trigger bar does not engage the sear in double action, but works fine in single action.

    Is the trigger bar spring supposed to hold the trigger bar “up” because it seems like mine has no spring tension and can simply flop up and down freely.
