Until recently I never did more than wipe down the magazines for my Buckmark, but recently I have had some issues of Failure to Feed with one of my mags. The first round will fire, but the gun will not feed in the next round. It appears that this has something to do with the mag, since it only has happened with one of my two magazines. Looking at the two side by side I can't see any difference or damage, so I thought maybe if I disassemble and clean the magazine the problem would resolve, but I don't see any way to take the magazine apart. Any suggestions?
