CZ P10 Assembly question

[SI VIS PACEM PARRABELLUM]

What other guns or parts where present during take down and reassembly? What parts where in the BOX at the start of take down? This is interesting.

MYSTERY SOLVED!

I was looking through my stuff and remembered I have a box filled with an assortment of pins of all sizes. One size looked like the mysterious tiny pin. I counted the ones in the boxe and in fact, one was missing... how did it end up in my cleaning boxe, that’s a mystery for another day...

Thank you all for your support and recommendations.

What about reloading issue?

[nadim]

I will test it again this week end. I believe I may have assembled a piece wrongly. Yesterday i have disassembled and reassembled it again and it seems to work better without the real bullets.

The good practice after reassemble:
[be sure chamber is empty, no ammo in magazine]
1. function check (no magazine inserted): 
- rack the slide, press the trigger, release the trigger -> you know action works
- rack the slide, press the trigger, don't release the trigger, rack the slide, release the trigger (reset), pull the trigger -> you know action / reset works
2. firing pin / striker test (no magazine inserted):
- rack the slide, muzzle up. Drop pencil with rubber end into the barrel. Pull the trigger (with muzzle up). Pencil should jump out from the barrel.
3. Magazine release button test:
- insert empty magazine, rack the slide (slide should stay locked back)
- release slide, drop the magazine (magazine should freely goes down from the grip)

If all works, your firearm is perfectly fine and will shoot live ammo for sure.
I do this procedure every single time after breaking pistol down. This is a tool which save lives... has to be in perfect shape 24/7/365

Very cool! Thank you Jurek.

One oddity about the P-10 pistols, and this is the same with the three I have - the pencil test is shows VERY little movement. Not like the others where it leaps a half an inch - this one quivers, all three...but they work.

The pencil test is a problem without a pencil cut down slightly to clear the extractor claw.  Otherwise, the claw drags on the pencil and gives a false indication compared to a pistol with a shallower extractor projection in to the chamber, per David at CGW.

Interesting, have never heard that before. I will have to shave the rubber!

[jurek]

I've never shaved the rubber for this test. And yes, sometimes pencil jumps out from barrel, sometimes moves 1 - 2 inched. Both results are positive. It's only because of extractor or shorter / longer firing pin.
The purpose of this test is to be sure the firing pin / striker hits the primer (to be sure you haven't screwed up the firearm after reassemble)

The material that the eraser is made of will also affect the amount of movement that you get.
