I took apart my two magazines to clean them and looked inside. Glock uses some kind of steel or metal insert inside the back of the magazine. I have only put maybe 150 rounds through each mag but there was obvious wear on this part (light scoring). I know you are not supposed to lube the mags with oil or grease. But i thought it might not be a bad idea to lube inside the mag by dusting inside with some (dry) powdered graphite. What do all you folks have to say about this idea? Is it just a dumb idea? Is there another lube i should be using, some compelling reason not to use graphite, don't think graphite will do any good and just leave it dry like Glock says?
