CZ 75 SP-01 CGW Pro Trigger Install

[j4ck404]

I finished this install last night and now I need to know… does this officially make me a man?

The hardest part was getting the hammer in. Seriously—did they have to make those pins fit like they were installed by Thor himself? I experienced the full range of human emotion getting those things in. At one point, a punch died in the line of duty.

The upside? The internals are no longer a dark mystery to me, and I actually learned a ton from the process. Growth. Character development. Trauma.

Then I moved on to my Beretta M9A1 and installed the new hammer in about five seconds. Five. Seconds. I actually laughed out loud.

Looking back, I remember thinking upgrading a Glock was “work.” That’s adorable. Turns out it’s basically adult LEGO by comparison.

If anyone else is doing this upgrade and hits a wall (or a pin that refuses to move), drop a comment—I’m happy to share tips. Also, YouTube saved my sanity more than once.

Sorry it does not but it is an enjoyable learning experience - once it's over. I've done one safety and two decocker CGW pro packages. Every time it's something different. The hammer pins popped right out the first time. It's worth purchasing a $10 hammer strut to avoid hours of frustrating pounding (I put mine in the freezer overnight and that seemed to do the trick). I've rebuilt the seer cage at least 10 times because something seems to always go wrong during installation. But it's given me confidence to try many more things on all my pistols. I made a video on YouTube of where the parts go because that was my biggest problem my first time.

Good job !! Next time if you want to be even braver try doing a 75 BD or P01 . I remember the first time I did a BD a buddy said “ if it’s your first time doing a CZ decocker and want to be braver …try do it without using a 1 gallon zip lock baggie and working inside it…..or have extra parts supply handy. The super super brave do the work over carpet and no baggie .

It's a good idea to order at least 4 extra L springs.

I have no problem with the hammer strut and disconnector spring whatsoever.
That's probably because my workbench is 1/2" thick plate steel and I push the pins out with an air-riveter with the hammer sitting on an aluminum bench block.
If your setup is not solid, I could see fighting those pins.

You only need to order 2 extras.
I still have the two extras I ordered because after you have spares, you won't lose them anymore.

Now THAT is an absolute fact.

I have cajunized an SP-01 and a PCR. Both were valuable learning experiences and I really appreciate the trigger when completed. Still, anytime I need to do a detail strip I have to go back to YouTube for the step by step.

For me the toughest part was putting together the sear cage assembly on the DA/SA models.

Having proper tools is the difference between a 2 hour nightmare and a 5 minute quickie!

If you have a 3d printer, take the extra time to print out a holding fixture or a vice fixture.

my tip for those CZ Hammer pins is a heavy duty Cone shaped punch and a heavy hammer. Also be mindful of your surface. If you're doing it on a flexible wooden bench, its just going to jump around and make things more difficult. early on i remember using wooden riser blocks on the concrete floor lol

Cheers

I had fun doing mine.
All started with 97B I sent to CGW for 1911 style bushing, barrel coating, and SAO conversion while at it. Two month later still didn't get gun back, tired of waiting and gave myself a word not to send guns for smithing work ever again. So I install PRO kits on SP-01 and P-01, did SAO conversion on 75B, changed trigger to CGW with reach reduction kit on PCR

Oh what fun it is to feel like smashing your head into the wall lmao i overhauled my tanfoglio. Worth it and in the future, if there are any issues, you already know how to take it apart and put back together

 

[Bear40]

It's a rite of passage.

now you NEED sp-01 kadet kit

I know exactly what you are talking about. I done one and the best thing is to take some grit sandpaper and in a circular motion smooth out those pins 5-8 minutes each. Add oil on the pins and those holes in the hammer and it should go more smoothly then banging the snack out if it with a punch

This is a true thing

My tip would be to make some slave pins for reassembly. Use roll pin punches when appropriate. Have a black sharpie nearby.

Also bandaids for when you stick the sear spring in your thumb

This is by far the best video I found on how to put together decocker sear cage. Downloaded and saved

Ditto!! You need a heavy steel plate and steel block in order to remove or install hammer pins easily. Cajun pins are tapered for ease of installation.
