I have a few low and/or consecutive serial numbered HKs. Low numbers are a LOT harder to get than consecutive numbers. HK makes no effort to mix up numbers and if you order several HK pistols of the same model and caliber more than likely you will end up with a string of consecutive numbers. We had 9 in our shop all consecutive. I bought a few consecs but then realized it is no big deal with HKs so quit doing that and with HKs anyway, it sure does not add anything to their value, unless the buyer is ignorant of the way HK ships firearms.
