I recently came across some magazines that I got in a deal. Only problem is I'm not sure what the belong to. All I know is that they aren't for any gun I own now, or have ever owned in the past. I'm hoping some GT knowledge can help me out here. The first three are identical save the rear of the mag. A 9mm fits well, but seems like it may be a bit short. A .45 ACP fits, but it doesn't seem right. Doesn't seem like it would feed well out of the mag at all. Here are the pics on the first three. The first three pics are of the same mag, the last pic is all 3 together. Again, identical except for the rear of the mag. the sticker in the third pic is hand written M-11 on it. I thought maybe that could mean they are for the Cobray M11, but I keep doubting it. They are heavy and feel quite stout. I think the handwriting may be wrong, or have another meaning. Any ideas would be well appreciated.
