Should they not expect this pistol they paid from a couple hundred to say a $1000+ to work right from box if needed . I think so.
I am not challenging the expectation so much... of course we all expect brand new things to work out of the box. That is a far cry, though, from the idea that we can *depend* on them to which is unwise and in 99.9999% of cases unnecessary (Hollywood blockbusters excepted...)
Any mechanical device is subject to fail out of the box a small percentage of the time, especially the more moving parts it has. That is just the world we live in. It only makes sense, then, that if you do intend to trust your life to any firearm that you would take some simple, common sense precautions beforehand:
1) know how to properly operate your gun (and READ THE MANUAL)
2) familiarize yourself with the proper malfunction clearing drills for your gun
3) practice steps 1 and 2 regularly to where you do not have to think about the "how" (dry fire!)
4) verify your gun works reliably with your choice of ammo (i.e. 250 rounds+ without any kind of malfunction is my personal minimum)
If referring to this procedure (particularly step 4) as a "necessary break in period" offends you then call it whatever you like, but there *are* sound reasons why this is recommended practice with any new carry gun, regardless of model or cost.
If the OP wanted to know what guns are generally considered more reliable out of the box then that is one thing. It is something else entirely to suggest that any such consensus be the primary basis for someone's feeling of readiness when it comes to protecting their life.
Yes, most gun owners do not practice enough (or at all) and most want to think the most critical choices they make as gun owners are which gun to buy or what ammo to use in it.
The truth, however, is that the biggest decision they ever make is whether or not to practice and be prepared!
