CZ Action Timing
« on: August 09, 2015, 08:58:34 AM »
A lot of you are curious of how most CZ 75 series pistols works.
In my case, I finally understood how a CZ pistol works from reading a lot here.
It is true that pictures says a lot. However if you can animate it, is even better to fully understand it. I  found a animation but did not show the details. So, I decided to make my own. It is not perfect, but at least gives you an idea how it works :)
NOTE: I have slowed the GIF so that you can see it better

Edit:

No problem.  It is my intent to share it so that the first time CZ pistol owners can understand how it works.  To be honest, I cheated a bit when I found the "old" armorers manual that shows part of the cut out view.  The rest was from pictures and scaled to match the work.

What magic spell is this?!? The picture is moving!



This needs to be a sticky in the gunsmithing section so we can tell future generations that it's the dark blue thingy not the red duhhicky.

I am in awe of this kinda a stuff, great job.

You mean the original CZ 75?  If it so, well is there since I used the original armorers manual cutout view as a base of the work.  :)

Updated version posted in the first post.

As you can see, I added a bit more detail and some bit more realistic look.

I added the 75B SA model going through the cycle. This one was a bit harder to deal with because no matter what I did I could not get SA to reset.

I modified the shape of the trigger bar humps, the sear. Another variable was the SAO trigger in which the hole location is a bit different. After working for about 3 hours it did occurred to me to move the notch in the slide 2 or 3 mm towards the back. This is what fixed the issue.

As you can see, I was being a virtual gunsmith. :)
Enjoy :)
