We all know, that if we walk into a store and buy 5 "identical" pistols one may be more accurate than the others, one may be more dependable than the others, one will break before the others, etc., etc., etc.
Fact of life. "identical" pieces are not identical.
But, it's nice to see it's possible to get a good one, at random. Both reliable and dependable. If it feels good in your hand then it's a great candidate for your new self defense handgun.
