Magazine for Double Stack Destroyer Carbine
I have a Destroyer Carbine in 9mm Largo that takes the double stack magazine. The magazines are like hens teeth. I have read that Sarco used to sell a 50rd magazine that could be modified to fit. I asked them if they had any and unfortunately not. I am wondering if anyone knows which magazines people were using to do this? If I know that then I can try and find some. I'm assuming it is some 7.62x25 submachine gun of some sort.
