Im in the same boat. Mine went back to Kel tec for FTE almost every mag. They replaced the slide and did a fluff and buff. Got it back and it FTF the 2nd to last round consistently. Round goes in nose up and jams on top of chamber. Tried my cousins mag and it was much better. They then had me exchange my 2 mags and it still does the same thing. last few range sessions its gotten a little better. Went today and had 5 FTF's in 100 rounds and that was better than last time. Using American Eagle but Im going to try different brand next range session then it may go for sale. Really shouldn't be like this. Cant say its me cause I've shot 2 others with no problems. Its almost not worth sending this thing in more than once, the shipping fees will start to be more than the gun cost.
