1) Welcome from Georgia.
Please take a few moments to familiarize yourself with all the sticky posts in the 'New Members' section. Together with the Help Topics in the 'Important Information' or 'FAQ' sub-section, these include 'how tos' such as 'how to' post pictures on the forum.
2) Sorry to hear of your issues. This is very strange and very unusual.
•
Very first thing.... Drop the mag. Clear the weapon of all ammunition that's possible.
If a live round remains in the chamber, then treat it as a
loaded weapon. It can still fire.
Also meaning keep your finger away from the trigger and maintain muzzle control at ALL times.
• Normally, I would suggest you mail this back to CZ-USA for warranty work, but you cannot mail a loaded weapon.
• When this happens on a 9mm weapon (which is somewhat common)....
While the muzzle is pointed in a safe direction, grasp the slide with a very strong grip...
And then pound on the butt of the hand grip with the remaining hand.
If your grip isn't that strong, then get some help. A gunsmith will be very practiced at this.
• If you do take it to a gunsmith, then you
must tell them that "the gun IS loaded !!"
Call before you go, so that they know to expect you.
Also, take the remainder of the ammo with you for inspection purposes.
• Resist the temptation to put something down the barrel to drive out the round... The ammunition can still go off !!
A detonation would drive the drift AND the bullet through your arm...
While blowing open the exposed portion of the brass, showering anyone nearby with hot gas and brass shrapnel.
Not a happy event.

• In the end, you will need a gunsmith to determine if the gun or the ammo was at fault,
before firing the weapon again.
Hope this helps.
