P10m locked up
« on: November 02, 2023, 06:08:41 PM »
I've reached out to CZ for warranty support, but wanted to hear what you think about this.
My p10m locked up while firing, slide is closed on a live round and trigger  is non functional.
I can move the slide back maybe 1/8 of an inch, but it hits something and won't go further.
Trigger won't pull and also seems to be hitting something.  What broke and any thoughts on how I might fix it, or at least get the round out before sending to CZ?

My P10M did this first time at the range.

It turns out that to a a bad length 9mm round.

Range gunsmith got it apart and we measured the round.

My mistake was buying a box of Summit brand factory reloads.

I did a drop test on the box of 50 and 9 were unable to fully go in battery.

Take yours to a gunsmith to get it safely apart and then drop test all of your ammo you plan on using.

I didn't see. He did it in a back room, I presume for safety.

I had an over length round jam up my gun at the range, too.  I followed advice I found on YouTube (always safe, right?) and (while pointed in a safe direction) got a good grip over the top on the slide with one hand, and with my other hand hit the grip forward as hard as I could.  It worked for me.

  One thing different- I don't recall any looseness of my slide when that happened, I don't recall any play at all, so is it possible OP has a different problem?  It does seem most likely an overlength round, though.

In my case these were my reloads, and the seating die had gotten loose and out of adjustment.  I went back through all the rounds I had made since then and pulled the bad ones.  That's one of the reasons why many people say don't rely on reloaded ammo for personal protection.

CZ said that they can't help because you can't ship loaded guns, so I dropped it off at my local gunsmith.  Well see what he makes of it

Certainly keep your finger off the trigger - it’s loaded.
Round stuck in chamber, slide out of battery. Always pointed in a safe direction and similar with Duke… Leather glove wrap/grip over slide and push slide/grip against each other (left/right hand push forward).
Worst case… Push the grip/frame with the slide top/corner (or rear sight ledge) against the wood shooting table edge. Don’t do this with poly sights. Basically, the slide is stuck from the jammed round.

I've reached out to CZ for warranty support, but wanted to hear what you think about this. My p10m locked up while firing, slide is closed on a live round and trigger  is non functional. I can move the slide back maybe 1/8 of an inch, but it hits something and won't go further. Trigger won't pull and also seems to be hitting something.  What broke and any thoughts on how I might fix it, or at least get the round out before sending to CZ?

It's all covered HERE.

The problem is not with your gun or with CZ. The problem is that you don't understand 9x19 ammunition, and this ignorance has allowed you to buy or handload ammunition that is out-of-spec, and therefore extremely dangerous to you and everyone around you.

• If the gun had been allowed to fire out of battery you could have lost a finger and/or an eye. At the very minimum, such occurrences are good for a trip to the ER.
• As it is you have a live round stuck half-way into the chamber. First of all, you must exercise muzzle control at all times. Then, drop the mag. Finally, you need someone with a grip (hand strength) like iron to grasp the receiver with their left hand (all the while maintaining muzzle control), and then pound the rear of the hand grip with their open right palm. This is the most practical way to eject the offending round. [This works well on hammer-fired guns, but may be complicated by the inner workings of the striker-fired gun.]

>> This may be the most important part: At that point you can examine the round and determine if it was 1) the case or 2) the bullet causing the problem. Then you can use that knowledge to educate yourself (and others) about the dangers of not checking your ammo.

• The case can cause the problem because the 9x19 Luger chamber is tapered. And just like a Morse Taper on a machine tool, any out-of-tolerance problem with the cartridge case greater than 0.001" can allow the cartridge to be wedged extremely tightly into the chamber.

• Or, your problem could be one of OAL. The CZ, like all eastern European guns, runs a short leade (aka freebore), and when you do not provide ammo made the correct dimensions, then the ogive of the bullet can be easily wedged into the beginnings of the rifling.

Only inspection for the ejected round will tell you the "root cause". It will be highly educational, and possibly a "lifesaver".

•• Now, your problem may be further complicated by the inner workings of the P10. I am not a gunsmith. My area of expertise is ammunition. Again, if you are going to buy OR handload 9mm ammo for a CZ, then you need to read the articles contained in the Stickies at the top of the Ammo & Handloading Forum. They are there for your education and protection.

•• Please share with us the name, type, brand, weight and stock number of the ammo you were using so that we can warn others.

Hope this helps.

It  sounds like it was an out of spec round, or in spec but out of CZ's spec, and you could fill a library with things of which I am ignorant.  I'm halfway through my third case of this ammunition, all 2500 rounds fired through my CZs, and hundreds through this particular pistol, none of which had any issue at all.
