Just a little more clarification - 59 and 69 series were in 9mm only per my understanding. The 59 series 14/15 round mags will fit and function in a 469/669/6904/etc but will be too long for the grip and protrude approx 1/2" or so. Conversely - the 69 series mags are too short to lock into/function in a 59/459/659/5904/etc. Either the 59 or the 69 series will fit/function in a Marlin 9mm Camp Carbine. Good luck ...
