I was able to get this PMX on sale and I definitely think it was worth it for the price.
The biggest selling point is the compatibility with the KMP9 mags that are widely available and reliable.
The plastic that the body is made from makes the SMG light but durable. The action on a full charge of propane is snappy and full auto is nice. I know that KWAs can be difficult to work on due to their proprietary nature, but since I'm leaving this stock for now, I won't make a positive or negative comment pertaining to how easy it is to upgrade.
Personally, I would have preferred a more standard flash hider with 14mm- threads, but I am aware there are adapters available to remedy this oversight. I think the sights are acceptable and the foregrip, which is similarly high quality polymer, is nice to have in the box.
