For the same reason the importance of proper care of the gun and using only proper magazines is emphasized again and again. The war in Afghanistan and Iraq reinforced the lesson that using cheap aftermarket magazines, even if the Government buys them on bid, can cause the finest pistols to jam. The advice is clear: Use only Beretta and MecGar brand magazines in these guns.
BIN-GO!! Something that the late great COL David Hackworth (R.I.P.), with all due respect, conveniently overlooked in his polemic hit piece on the Beretta M9 in his column in SOF Magazine.
