Out of the box mine was perfectly reliable until it started getting dirty/greasy after just one box of ammo, then the FTE and FTRTB issues would start. Cleaned it well, it would then go just under 100 rounds. Then I took apart the guts of the slide and found a bunch of crap in the striker/extractor channnels. Cleaned it out and de-burred the holes, now the pistol usually behaves until it starts getting REALLY dirty at about 200 rounds. With these tiny guns there's no tolerance for dirt, burrs, or metal shavings in the action. Take the pistol completely apart, clean it GOOD, lube it with something that won't run out (like gun grease), find a good carry round (like Hornady Critical Defense) and it should run fine.
