Trigger Pull: The trigger pull on the KWC Colt 1911 M45A1 Blowback Airsoft Pistol is what you would expect from a true single action 1911 styled pistol and typical to all the other KWC 1911s 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 KWC Colt 1911 M45A1 Blowback Airsoft Pistol, I imagine it should perform well considering it has adjustable spin-up/hop-up. According to the manufacturer's claimed FPS, we should get somewhere in the mid to high 300 FPS range using .20 g plastic airsoft BBs.

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 KWC Colt 1911 M45A1 Blowback Airsoft Pistol seems to have a bit heavier finish on it. It looks really good and seems to be holding up well.

Realism: The KWC Colt 1911 M45A1 Blowback Airsoft Pistol is a close replica of the real steel Colt 1911 M45A1 in almost every way other than the fact that it shoots 6mm airsoft BBs 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.


  • 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
  • Finish on the Cybergun and KWC guns can wear off on the high points

Comments: 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 their 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.

Boss of the 1911's

1st of all, I ordered this during the Pandemic and was able to receive it within the same week. Thanks for the fast shipping. The gun itself should speak for itself and if you are a 1911 enthusiast, this is really close to the real one in term of detail. This is the Military model and you just gotta have it. Cybergun /KWC you cannot go wrong. The slide sounds good every time you shoot it and very snappy as ypu can always expect from KWC 1911's.

100% accurate to the real thing!

I saw the M45A1 on Replicaair and just had to have it, this gun has a beautiful finish to it, feels very real/premium and fires so nice out of the box, you could adjust the hopup to have a tighter grouping but i was able to get a 1 inch grouping 25 feet, nothing impressive, but hopefully you can gauge for your self just how nice this gun is by those numbers. I would highly recommend this pistol to anyone looking for a true replica to the real USMC M45A1
