My NPAP M70 came with two magazines; one polymer Tapco and one metal (I'm guessing Korean?). The metal one fits just fine, however, I don't like the feel of metal magazines. I guess it's a texture thing, but I've never liked them. The Tapco magazine fits pretty good, but there is just the slightest bit of wobble when inserted. I was thinking about trying out some Pmags. Does anyone have any experience with them? They seem to run about $3.00 more than the Tapco mags, which isn't too bad.
