Trigger Pull: The trigger pull on the ASG/KWC MP9 A3 is single action only as the charging handle has to be pulled back to open and release the bolt for the first shot. There is a trigger safety but it is not noticeable when shooting this Airsoft machine gun. There is a short take-up and then a light release and short reset.
Accuracy: Right away I put my NcSTAR 1x25 Red Dot sight on the ASG/KWC MP9 A3 as it was a perfect fit for this small and compact machine pistol, it did not take long to sight it in and I was able to get decent accuracy in both semi auto and full auto burst due to the mild but very fast cycle rate. I was able to get a 2 inch grouping at 30 feet out using a rested position. In full auto mode the grouping did not really get too much wider. I also got between 350 and 370 fps when testing the ASG MP9 on my Chronograph.

Build Quality: The ASG/KWC MP9 A3 Airsoft Machine Pistol is built very well, using similar components that you would find on the real steel version so yes it has a plastic shell but that is to be expected. The ASG/KWC MP9 A3 does use lots of metal where it needs to be like in the internal parts, pins, bolt, barrel, rails and even the magazine. The fit and finish is near perfect!

Realism: I have to say the ASG/KWC MP9 A3 is pretty much a bang on copy of the real steel Brügger & Thomet MP9 A3. The only telltale sign is the ASG branding on the right side along with the 6mm caliber beside the ASG logo. One other small detail is the magazine which is metal on the Airsoft version where as you would find the real version uses a transparent polymer magazine.

  • Extremely fun to shoot and it sounds awesome!
  • Rate of fire is very fast and does not slow down much even when the gas is running low.
  • Good overall power for a short barreled gas blowback gun.
  • Very nice trigger with working trigger safety.
  • Excellent replica of the real steel version in just about every way.
  • Can add a lot of gear and make this gun your own.
  • Decent price for all you get out of the ASG MP9!


  • Bolt didn't lock back for me when the gun got really cold?
  • Real magazine would actually be transparent polymer.

I really like the ASG/KWC MP9 A3! I love the look, I love the features and the price is also really good for what you are getting. I was really impressed with the super high cycle rate and because of the small low weight bolt the gun does not move around too much or slow down in rounds per minute even when you do a full mag dump. There is however just enough blowback recoil to give you that GBB realistic feel! I also found that the magazine holds a lot of gas so it is possible to get two magazine worth of shots out of a single fill, that's around 100 shots. I also like how easy it is to add to the ASG/KWC MP9 A3, I had mine pimped out and looking amazing right away and suggest if you get one you do the same :)
