"I bought the KWA MP9 with one goal in mind: Run a high-speed loadout with minimal gear so as to literally outrun the enemy and show the uppity Milsim guys that a $300 loadout can keep up just fine with a $1500 loadout. I hate to admit it, but that is not a very Operator thing to do. On to the gun. In the few months I have had it, this gun has done what I hoped it would and more. If you are looking for a great SMG, look no further. The MP7 is a great alternative, but its body is neither graceful nor lightweight. The MP9 feels like an extension of the body, everything is fluid, there are no sharp edges, and it weighs less than my USP tactical. If the hop-up is just right, you will have no trouble reaching out to AEG range. Be warned, however, that the mags are expensive and when you run dry of BB's, not even the speed loader can save you unless you packed the awkwardly-shaped can of Green gas or Propane. As any air softer would say- Why not buy more mags? If you want to carry even a mediocre number of ready mags for your MP9, you will spend the gun's price on the glorified paperweights. You have been warned.

Super loud, I have gotten many, many comments, good and bad, on the noise.
Very lightweight, easy to acquire targets and move the weapon quickly.
Balanced, due to magazine being placed in grip.
Due to short barrel, I don't have to worry about muzzle-sweeping my friendlies.
Unbelievably reliable.

Due to loudness, my position is pinpointed easily.
Feels like a toy without mag.
Accuracy is, as one would expect, not the greatest.
Mags are expensive.
O-ring in bottom of magazine will fall out. Bware.

Overall, 8.5 out of 10 due to mags and somewhat cheap feeling. I would recommend to someone just beginning to use a GBB weapon as a primary. I am only replacing it due to a shifting play style (with a VFC 416) and a need for more accuracy and firepower. Buy it for plinking or a fun secondary if you feel handguns are too mainstream.

"This is the Manny Pacquiao of the airsoft world. Even though it's small in stature, it hits like a dump truck while putting on quite a show. Had mine for years now and it's the best gun I own.

. Phenominal accuracy and power for it's size.
. Legendary KWA reliablity
. Aftermarket upgrades are available. Rare since its a KWA.
. This gun will make your ears ring while its instilling fear in the enemy. The satisfying crackling pop it makes is perfect.

. Shoots too fast for indoor fields without a CQB Bolt or Flute valve installed.
. Hard to aim with if you use a full face mask.
. Mags are expensive.
. Orange tip is obnoxious (there are threaded adapters that fit over it though)

Overall, this gun is straight up force multiplier. You will be feared after fielding this monster. I haven't had any problems with my gun yet and I'm glad I got it!

"Although I haven't used this machine pistol more than a couple of times over the past 18 months, its few uses have been enough to strike fear into the hearts of the opposition. The KMP9 has a distinct noise that can be identified by any player with a keen ear.

The KMP9 is actually perfect to a fault. Its powerful NS2 gas system sends hailstorms of BBs flying at an enemy at roughly 400 fps. That is impressive, considering its inner barrel length of 140 mm. The externals are just as amazing as the internals; the entire receiver is made of what seems to be nylon fiber or something of the like, and rail space is provided on top and on the right side, perfect for optics and flashlights. Plus, the full-size magazine carries 48 rounds, while spare 48- and 20-round magazines are available for purchase on

On the downside, spare magazines and the fps-reducing bolt assembly are very expensive. Typically, these items cost roughly fifty dollars. Then, for someone who has never bothered the KMP9's internals before, it can be a bit of a headache to disassemble the gun; the fps-reducing bolt assembly isn't really a drop-in piece, since it takes several minutes to disassemble the gun to install the piece. Aside from that moment of difficulty, the gun performs well, and its loud roar and insane rate of fire will continue to terrorize the enemy teams for years to come.

- Durable, quality internals and externals
- 48-round magazine
- Adequate rail space for optics, laser sights, and flashlights
- Foregrip
- High rate of fire
- Loud

- Expensive accessories and parts
- The fps-reducing bolt assembly takes some effort to install, but it's well worth it.
