>>Pssssst, Chris...
The problem with that mag, and a couple I had, is that the lips were too narrow, not wide. Optimal seems to be about 0.320". Karl says that + or - 0.005" is ok. My problem mags were like 0.011" or so as I recall. I simply widened mine to the desired 0.320" and now they work fine. I thought you made note of this on your Rohrbaugh quick reference site...?..TW<<
