Stovepiping

[SI VIS PACEM PARRABELLUM]

Good points. My ejection distances have probably been  in the 15 to 20 range. I had two more stovepipes today, one with a fresh round stoping at about the point where the bullet touches the inner top surface of the barrel firing chamber, and the other with a fresh round entering the barrel while another was on the feed ramp. Good notations about the headspace issues in cz's.
        A second gunsmith felt that the trigger is atrocious and that the ejector is probably questionable. I went ahead and left it with the 'smithy to work on because we at least agreed on the trigger action.  Let's see if there are any favorable changes next week.

You stated in your initial post that this was a new gun. You should really contact CZ USA as it should be under warranty and allowing some one else to tamper with the gun could void that warranty. I've had to use the CZ warranty in the past and the service is great. Let the guys that really know the gun fix it the right way.

+1 to this.  Short of having someone make modifications to your gun and voiding the warranty, you can safely and easily replace the recoil spring to something a little lighter -- that's what helped me at least with my P-07 which had a pretty heavy recoil spring.  This is a very inexpensive and quick way of seeing if it's just that part.  It'll also help with racking the slide easier.  Check out Cajun Gun Works first:

Walmart has ZQI nato 9mm which is fairly hot, break it in with that @ $10 a box you can't go wrong.

Dang! Excellent point about screwing up the warranty. If I had to do it over......  I can only hope for good luck.

I had a couple of rounds stovepipe/stick on the feed ramp  over the first few hundred rounds through my P01.  Since then though, she has run like a champ and has been 100% reliable.

I think the mainspring that comes from the factory needs to be "broken in", probably spec'ed for +P loads.

My $.02 - shoot and enjoy it.

Any updates?

Just got the CZ back from the gunsmith, who said that the ejector was a somewhat loose and in need of a little reshaping. There were also numerous sharp edges at the chamber end of the barrel. He rounded, smoothed, and polished the chamber end and ramp. The first hundred rounds of Remington brass have worked perfectly.

The ejector is an integral part of the sear cage so how can it be "somewhat loose"? The sear cage is held in place by the shaft of the safety lever. How would one correct that looseness? Reshaping was probably the solution.
