Being a long time KWA fan and owning a number of their GBB pistols, I knew the KMP9 would be amazing… I just didn’t know it would be this amazing.

I received the KMP9 from my good friends over at Airsoft Extreme, courtesy of SoCal Airsoft League. Out of the box, the ergonomics when holding the KMP9 with the stock folded is what stood out most. Very natural and very comfortable. Racking the charging handle gave a very satisfying clack and firing from the closed bolt position gave me hope that foreign object obstruction would die with the venerable MAC11A1 series.

Performance is where the KMP comes into it’s own. While designed to be a CQB monster, the KMP9’s high velocity and outstanding hop up make this little SMG a field worthy weapon. My tests did not fare well with .20g bbs as the flight pattern appeared to be all over the place. When I stepped it up to a .25g bb, the KMP9 began to shine. I was hitting a man-sized object at 100ft with minimal hop up with absolutely no problem. With the FPS being so high on propane (average 387 w/0.20g bbs) you may run into problems when deploying in a CQB environment, but for field play, it’s a blessing. KWA does offer a Low Power Bolt for the KMP9 which will reduce the velocity by 50-70fps, making the KMP9 much more CQB friendly. Also be aware that the noise made when firing will turn heads on the field, and brown the shorts of the opposing team!

KWA hit a home run with this little monster SMG! So much so that I acquired 3 more magazines and run it as my secondary whenever possible. Definitely recommended for all those looking to get into the GBB SMG scene.
