I have a .30 cal Crown Gen2, that I purchased a couple of extra mags for. The new mags are identical to the original, but are very tight to install. As a consequence the feed hangs giving me a dry shot.
Having enough of that foolishness I got out a sheet of 400 wet or dry sandpaper, laid it on a flat surface, and polished both sides of the feed corner of the mag with good results.
