    Well made and it does fit a J9 as it says, but this has a few design flaws that lets it down. The screws don’t quite fit the slots their ‘designed’ to fit, also the actual mag catch itself should be a solid piece like the original JM9 as it has a tendency to catch on the gearbox when depressed not allowing it to fall back into its place, this would also take the user out of the equation having to adjust where it sits. Apart from that, this is a good addition to a JM9, and hex screws are much better than philips when constantly being undone to service/modify.
