I have a Kahr K9 that is far outside the date range in the list. The serial is BF48xx. According to the chart it should be 2009 dom. But Kahr told me via email it's a 2017 dom.
I have a K9 Elite S/N BF04XX. They told me on the phone it was built 8/31/2007.
Number 48. Just acquired it used from a dealer many years ago. Never noticed the serial number was unusual till a few months ago.
That's pretty neat. I really like my early model. I won't carry it, due to rarity, but it seems to be a really good weapon, trigger shape is a little nicer than my later model.
