Well, all I can say is that was the information presented to me over the phone by a company representative. I bought mine used, in '95. As noted, there's nothing in the manual regarding maintenance intervals. So....... since I intended to use the thing as an actual carry gun instead of a place filler in a Kahr hobby collection, I decided to get a hold of the company. I guess I could have plumed internet forums for some tidbit of cyberweb genius, but the web wasn't the cornucopia of wisdom it is now. Funny me, I just called the folks who made the thing. For twenty five years I followed their advice and the little gun ran without issue, in all kinds of conditions. But hey, you do you bro.
