And maybe you will: they should.
SwampWolf, I am with you on this IF the gun's price is on the high end. When you price your product as top of the line, it should perform like top of the line.
However, I think when a person buys a cheaply-priced gun, such as the Kel-tecs, they should understand that sometimes the term "break-in" implies that a lot of the extra work, quality control, testing,etc. has been somewhat dampened down in order to seek a competitive price advantage. At least, that is the approach I take. The new guns I have purchased include a new Colt 1991 and a new SIG 239, along with four Kel-tecs.
With those guns, I took your approach with the first two - I field-stripped, cleaned and oiled, and expected them to perform from day one, and they did.
With the Kel-tecs, I took my approach and, after the clean and oil, I invited them to the range for the break-in rounds. Probably with some luck involved, the few problems I experienced with the Kel-tecs went away after anywhere from 50 to 200 rounds.
