Thanks guys!
Ahh - haven't shot it YET - maybe today, as I got my new S&W 1911 and a trip to the range is in order!
I did call Kahr about the serial numbers - lady who called me back said "the number ranges are assigned by BATF". "KD is a recent manufacture".
Mine is aluminum receiver - which is love/hate right now, I do enjoy the less weight, but it is..well - Alum! I traded in a shotgun for this 1927 and the pistol - so I had very limited choice at this store. Anyway it is a very solid piece, and 'they' have been making these lightweights for years - so I am keeping my fingers crossed. I just got a plastic case and horizontal fore-grip from Kahr - only took 2 days to get here! 30 round mag was back-ordered, though I ordered 5 more from another vendor. Hopefully Kahr has listening to complaints, as it appears this well made - and is tight! So far I did get to hand-cycle a few rounds with no problems.
Really is a nice looking piece - I will get some pics up ASAP.
