I'm going to take a stab at an answer.
The oldest reference to a TP9 I can find is in 2006. The "T"s first appeared in the early 2000s, so my guess is that the TP first appeared shortly before 2006, maybe 2004 or 2005.
The T series, going by serial numbers, are produced in pretty small numbers. Only a few hundred or so even less per year. My full frame TP has a low serial number and I bought new in 2009. I assume the change was made that year, (2009). Therefore, my guess is that Kahr produce only several hundred short frame TP9s. Maybe as few as 500 in the four or so years that size frame was used.
Any T series is rarely seen. I've never seen one in a store. I bought both my T9 and TP9 off the internet. Good guns, worth finding, IMHO.
