Purchased new end of August this year. I experienced many, many failure to extract issues using 3 brands of FMJ RN 95gr. Blazer (brass), Magtec and Remington. I called KT and they sent me a new extractor but it did not help. Called again and they had UPS pick it up on Oct. 5. Got it back yesterday and the work order said they polished the feed ramp, replaced the extractor and recoil spring and guide. Off to the range this AM and fired 12 rounds (most ever without a jam) and the 13th failed to extract. A new round stripped of the mag and jammed the gun. I was able to drop the mag and the fresh round dropped through the well (just like all the other times) But this time I could not pull the slide back. I took it home pulled the pin and removed the slide but was not able to remove the barrel. Called KT and spoke to Mike a very nice gentlemen who showed real concern that it had not been properly repaired. He asked me to try to reassemble it and he would email me a UPS prepaid return label. Well I could not assemble the slide to the frame-it would not go back far enough to insert the pin. After studying the frame a bit I noticed the hammer was down, I pushed it back and was able to reassemble and eject the fired case. I am now waiting for my email so I can send it back again. Normally I have very little patience for this kind of thing but I am so impressed by the customer service I am receiving from KT. Every one I have talked to at KT is very professional and polite. From what I have read in this wonderful forum KTs are great guns but every once in a while a bad one gets through. I am confident they will get this little thing running correctly. I have been carrying conceled since 1970, this is my first plastic gun and I just love the concept. Thanks for listining
