As you can see, I’ve got something of an issue with a brand new (as in unfired) Kel-Tec Sub-2000. I’m not particularly perturbed by the problem, which may not even be a problem, eventually. Any excuse to go to the gun store’s OK with me. But I’ve got a one Mulligan gun purchase policy. If the next Sub-2000 through suffers from QC issues, or if my gun store can’t find the time to find the box for a new gun, my business will quickly gravitate elsewhere. Where’s your point-of-no-more-returns? How many times have you reached it with which guns?
