About the CPD mags. I have two 30 round and two 10 round mags. I only have Wolf ammo. I haven't gone to the range to test the mags yet. I just hope they work and feed. They loaded, ONLY with a speed loader and I tried to see if the cartridges would push out of the mags just by hand and nope. The springs are so stiff, they are pretty much impossible to load fully by hand, or unload unless you're a model T800 or greater. Hell, I couldn't even unload them with the speed loader just to see. So hopefully they feed fine.
