Out of the first 250 rounds I had 47 FTF's, all of them were light primer hits. Had several stick on the feed ramp even though it was polished. When I was shooting my personal protection rounds (Win Ranger Talons) It would not strip the next round out of the Mag, and no I wasn't limp wristing it. I was getting the FTFires from the first mag on and through 4 brands of ammo. Kel Tec has had it for two weeks now so I hope I get it back pretty quick. I like the gun and the feel, but I got to trust it.
I hear ya, I know many people believe the "break in period" is bunch of cowpie, and maybe it is, I don't know. The fact is, an item used for protection of life should work the minute you need it or don't, regardless.
I won't lie, I did have problems rite out the box, and who wants that? Not me. I put a lot of rounds through it before I figured loose retaining pins and screws were also a potential issue.
She's a bit "snappy" but i've since added the screws to the frame (from the belt clip, I used loctite), added a hogue grip(this helped with bite to my hand, that serrated back strap is sharp), and had to re-tighten the extractor screw (with loctite). Many series of events with this gun while shooting on occasion and adding this or that (screws,grip, etc.) Man now that I think about it, that really sucked! Oh well, I must like the abuse,.... I'm happy now.
I hope it works out for you.
