Hi. That sucks. You need to contact CZ USA and have them pick it up. Request UPS or whomever they use to pick it up to save you postage. It's legal to do coz you are shipping to authorized warranty /repair station. Pistol will ship right back to your house from them when fixed. Brand new gun with Warranty card, there should be no questions. If you can't find contact for CZ USA I should have it posted before you log back on.
