Kahr Magazines - What company makes them?
I don't see any other markings other than Kahr on them.
SIG used to exclusive use Mec-Gar and the magazines had a Mec-Gar marking. Although there was a time earlier when the magazines were made by another company likely in Germany. Now they use a mixture of Checkmate and Mec-Gar. The Checkmate magazines are not marked except for the SIG markings designating model and caliber.
So, what company makes the Kahr magazines and has that changed over time from when Kahr first started? The very early magazine I received with my first Kahr (only Kahr for now) simply said "Kahr" on it. The newer ones also say 9-7 which I assume is caliber and capacity and is a change that came when Kahr expanded into other models and calibers from the Original K9.
