Kahr is in Worchester MA.
I've owned a few Kahrs, eight all total, most of them 9mm. I hate to say that I've had some not so good experiences. A couple had feed and eject issues, one had lightstrikes, two models broke followers and one experienced a broken trigger bar. This is all over thousands of rounds but compared to some other brands, the Kahrs have just never performed up to a level I could trust. Of the eight only one, a T9, never gave me trouble. Therefore I relegate them to range gun status only.
The current prices on some of the polymer Kahrs are very good and one may want to chance a buy. Just know they are not perfect. My personal favorites are the TP9 and K9.
