Trigger Pull: The trigger pull on the Cybergun KWC Colt 1911 M45A1 CO2 Blowback Airsoft Pistol is what you would expect from a true single action 1911 styled pistol and typical to all the other KWC 1911's on the market. It has a short take up and then a nice light and crisp release. The working grip safety is a nice touch requiring your palm to be pressed against it for the trigger and hammer to operate..

Accuracy: At this point I have not shot the Cybergun KWC Colt 1911 M45A1 CO2 Blowback Airsoft Pistol, I imagine it should perform well considering it has adjustable spin-up or hop-up. According to the manufacturers claimed fps, we should get somewhere in the mid to high 300 fps range using .20 gram Plastic Airsoft BB's. I'll add this one to the list of airguns I need to field test review!

Build Quality: Most KWC built full blowback airguns are built pretty well with an almost all metal build and good overall fit but sometimes the finish can wear off a bit especially in the high points. The Cybergun KWC Colt 1911 M45A1 CO2 Blowback Airsoft Pistol seems to have a bit heavier finish on it. I looks really good and seems to be holding up well.

Realism: The Cybergun KWC Colt 1911 M45A1 CO2 Blowback Airsoft Pistol is a close replica of the real steel Colt 1911 M45A1 in almost every way other than the fact that it shoot s6mm airsoft BB's rather than 45 auto bullets :) The only real notable cosmetic difference I saw was the rail having less notches in it. Other than that it is bang on including the layered grips.

  • All metal construction - Good weight and solid feeling gun.

  • Nice heavy blowback action.

  • Very Accurate 1911 M45A1 styled replica.

  • True 1911 Single action trigger, excellent pull, very smooth and light.

  • Accurate trigger design and working grip safety.

  • Lots of tactical upgrades on this version (Tac style trigger and hammer, textured grips, ambidextrous safety, white dot sights, Rail for accessories)

  • Love the desert tan color and layered grips.


  • Sacrifice fps and shots per CO2 because of the heavy blowback but worth it.
  • Finish on the Cybergun and KWC guns can were off on the high points a bit but some people like the look.
  • Comes with the orange tip (I took mine off).


I have always been a big fan of the KWC line of full blowback airguns and this one is no exception.  It's kind of interesting that KWC does not seem to make there own blinded out versions of these guns and that a company like Cybergun is distributing them? They do look really great and this entire line with all the variations and new models will for sure keep selling these airguns. And they don't just come in Airsoft versions, I will also be taking a look at some similar 4.5mm Steel BB KWC made airguns shortly!
