Actually, on the subject of the mags, I was wondering if I could get something cleared up about Spyder mags not using the U-system (or whatever it's called) that Rap4 uses. I've heard several theories and wanted to know if any or all of them were correct. Is it mechanical (the U-shape is apparently unreliable), cost (the straight mags are simply cheaper to manufacture), or legal (Rap4 owns some sort of patent or copyright over the system)?
Not really life or death, but I've been curious ever since the MRX came out and no one made a mag this style for it. And it would be a neat addition on the underside of the Hammer without going as long as I imagine the 15-rounders are going to hang down.
