Disassembled, cleaned and reassembled my CZ P10.
When I was done I was left with a tiny pin and couldn’t figure out where it comes from.
Went to the range and after I pulled a shot, the next bullet didn’t reload automatically in the chamber..
Any assistance would be appreciated..

How far did you take it down? A pic of the pin would help.

Check this thread, but if you don't know your pistol yet, Earl Keese got the point.

Yes, I did follow the instructions on YouTube and did a thorough disassemble.
Thank you Earl. I’m trying to figure out how to post a picture on my iPad

Nadim,
try simple test.
Load magazine with dummy rounds, load and rack slide several time until locks back.
If all rounds get out from magazine and chamber, we at least know it's action, not magazine problem.
-
Thank you Jurek. Will try it right away.
-
Ok, no problem with loading and racking. Works fine.
-
So the other tests have to be done with life ammo at the range.
1. Load magazine with 3 - 4 rounds, load and rack slide several time until locks back (the same as you did with dummies)
2. Load single round to magazine, load, take a shot. Slide should lock back.
3. Load two rounds and take a shot, if possible take another. Let us know what happens.
Do these steps with all magazines you have with the gun.
Definitely we need to see the pin you found after reassemble.
-
Yesterday I was at the range. After the first shot, it wasn’t reloading the next bullet automatically.
Anyway, I will try again.
The pin is like a dowel pin, super tiny, like 5-6 times smaller than the front coiled pin, and 4-5 times thinner. (Sorry the forum doesn’t allow for posting pictures)

How to post pictures:

Did you do basic field strip? In that case there is no pins that you could find loose.

Are you sure that came off your gun? Your pic shows a slotted pin. All the pins in the P-10C that I know of are either solid, coiled, or that vibration resistant slotted pin (the one that looks like it has teeth) for the backstrap.
-
After I reassembled the GUN, that tiny pin was left in the box. I reviewed the you tube instructions 3 times, I studied and reviewed the diagram but couldn’t find that piece. What puzzles me is when I was testing it on the range, something was wrong. I’m thinking now I could have reassembled one piece the wrong way...will review one more time. The mystery is still that tiny piece...where did it come from?
Many thanks for your feedback much appreciated. Will update you guys next week end..

I’ve never seen that pin in my p10 before
-
This one IS NOT from P-10.
Looks like Firing Pin Retaining Pin from hammer fired pistol.

Anyway:
1. I don't think your shooting problems are related to this pin
2. try to find out how come this pin was found in P10 box :o ???
-
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?
-
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. ;D
-
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!
-
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.
