Agreed. Things should not require a break-in to become reliable. Break-in happens with pretty much all new machines, but should be reliable from the beginning (although it may get "smoother" as it breaks in).
Imagine a car engine that stalls and stutters occasionally, and fails to start at other times when new. Would that be acceptable? No, of course not.
What about if your brand new fridge stopped working once in a while, causing your prized steaks to spoil, and the manufacturer told you to wait at least several months before calling them again, causing you to lose thousands of dollars in food - not to mention having a hungry family? Unacceptable.
It seems that the more expensive, higher-end pistols tend to need this "break-in" to become so-called reliable. That makes no sense. Cheaper pistols skip a lot of the personal attention to reduce cost, yet unreliability in them, even three or four non-ammo related malfunctions when new, is considered to be quite unacceptable. I don't understand why we should accept such things in a four figure pistol that is almost completely hand-built and fitted. What exactly are they doing with all those labor hours? Plus, with modern computer-aided design and machining, what excuse do they have anymore? They should be able to fit it precisely the first time.
I'd love to get a nice, pretty custom pistol one day, but this sort of stuff always concerns me. I'd hate to have an unreliable pistol that I have to lie to myself to convince it is still a great pistol. I think several 1911 manufacturers, plus the "original" GI 1911 have shown that the 1911 doesn't have to be inherently unreliable. It is this strange obsession with super accuracy that has led to manufacturers to tighten everything up to the point where the darned thing doesn't even work anymore. Even then, it is implemented seemingly unevenly during manufacturing. Does not make sense.
