I currently run a machine shop specializing in composite machining so modification is still a possibility . If the standard catch was made to work why would the aftermarket mags not work? $75 is $75 plus I would still also be buying new mags at $40 each. so that $75 saved is 2 additional mags. I am married and Firearms are not a big priority on my wife's list of things I should be spending our money on.
