For only those of you that actually own a Tisas / SDS / Zigano pistol and have needed it to be repaired while under warranty what were your experiences in dealing with them or their designated repair facility ? Any first hand ownership opinions are welcome as well, good and bad. I'm considering an SDS / Tisas M16 9mm. I am aware that they are made in Turkey . Please limit comments to just this company's products. Thanks all.
