My neighbor brought over a S&W M&P 9mm magazine with the numbers 1-7 stamped on the mag body. Said he could not get it reassembled. Did get it assembled but when I tried to load it the floor plate went flying off. This particular magazine has the plastic sub floor plate with the two nibs on one side and the small tab that locks into the floor plate. I can get it assembled but as soon as I load or attempt to load it the baseplate comes off. Tried you tube videos so I know I'm doing it right. Mag spring seems excessively strong for so few rounds. Anyone have any ideas as to these magazines??. Thanks,Frank
