Trigger Pull: The trigger pull on the KWC Metal Slide CQBP M45 A1 Non-Blowback CO2 BB Pistol was about medium to hard but I have definitely experienced heavier trigger pulls on some guns. It is nice that the trigger is in the style of a 1911 and not your typical lever styled trigger like you will find on some 1911 wannabe's. I imagine if the CQBP M45 A1 has a lever style trigger it would have more leverage and be a bit lighter.

Accuracy: I have not shot the KWC Metal Slide CQBP M45 A1 Non-Blowback CO2 BB Pistol but expect it to perform similar to the Cybergun Sig Sauer GSR Sigarms I reviewed a while back since both guns have similar internals so for now until I do my dedicated Field Test review you can read my Cybergun Sig Sauer GSR Sigarms Review: "Accuracy was decent but not outstanding, I got around a 2.5 inch grouping from a 20 foot away free standing position, shooting just to the left and high on the target. I did find that I was able to zone in a bit better with the Cybergun GSR as I got used to the trigger. I also put the Cybergun Sig Sauer GSR through my Chrony Chronograph and got very close the manufacturers 397 claimed feet per second, actually starting off well above it and settling down to around the 370 FPS mark. My 8 shot average on a new CO2 was actually 422 FPS."

Build Quality: You will find a pretty nice balance of metal and plastic on the KWC Metal Slide CQBP M45 A1 Non-Blowback CO2 BB Pistol. The metal slide, magazine barrel and some literals give it a really decent weight in the hand and the fit and fish feel good overall. The trigger and hammer are not the best aspects of the gun in terms of quality as they are both plastic and both kind of made more for show and less for function.

Realism: The KWC Metal Slide CQBP M45 A1 Non-Blowback CO2 BB Pistol looks and feel the part of a M45 1911 A1 including a full size drop out metal magazine, working magazine release and safety. The slide catch release is none functioning and so is the hammer which does not cock back for single action shooting. It would have been nice to have a single action trigger and a working slide to finish off this pistol but it is meant to be more of an entry level pistol at the end of the day.

  • Good overall weight considering ABS receiver.
  • Metal slide, Metal Magazine, Metal internals.
  • All metal magazine holds CO2 and Airsoft BB's
  • Nice tactical 1911 A1 replica, looks the part.
  • Should have good FPS and lots of shots per CO2 based on my 4.5mm BB version testing!
  • Rail for mounting accessories.
  • Nice white dot sights.
  • Recessed barrel give it a more realistic look.
  • True 1911 style looking trigger even though it is double action only.
  • True 1911 working safety.


  • No blowback - slide does not move either.
  • Hammer moves but does not cock so no single action shooting.
  • Non adjustable rear sight.
  • Trigger action is bit heavy and long so it’s not going to be the fastest action shooter.


If you're looking for a lower cost well made 1911 in that classic A1 style but with a little bit of updating like having a Picatinny rail and tactical sights then the KWC Metal Slide CQBP M45 A1 Non-Blowback CO2 BB Pistolmay just be right for you. So it doesn't have blowback or a working slide, on the other hand it has lots of metal on it giving it good weight and feel and with less moving parts there will be less to go wrong down the road. You can also expect to get fps into the 400 range with a decent amount of shots per CO2 so the trade off not having blowback may be worth it for this reason. All in all a nice airgun in the under $100 category.
