I've been thinking of getting a couple of the beretta 92 30 round mags for my sub2k. I've heard only the Glock high cap mags work well. But being that I live in Canada the mag will be pinned to 10. I'm just woundering if anybody has tried them, and how well they work? I would just stick with standard 10 round mags, but I want to be able to attach two mags togeather for quick reloading. The 10 rounders fit flush on the bottom of the grip so I dont think I could make it work.
