My shadow 2 is in warrantee repair for second time now for failure to extract. First repair was stronger extractor spring and polish and adjust extractor. This helps reduce failures but not 100%. Polish appears to be back side of extractor. What does that do? Adjustment of same is a mystery also. I don't care to hear about cleaning or ammo type etc. My Hi power nor my HK fail to extract ever never! Regardless of bullet brand or bullet weight reload or factory. I don't want to be required to buy and sort ammo to find the one this $1500 gun likes. Reading these posts tells me CZ needs to find the 100% fix. Can't wait to try their second fix attempt.
