Trigger Pull: The trigger pull on the KWC Model 226-S5 Sig Sauer CO2 Blowback Airsoft Pistol is what you would expect from a blowback pistol with true single action capability. nice and light with a short take-up in single action and also decent when shooting in double action which for the most part you will not be doing since the blowback pre-cocks the hammer for single action shooting.

Accuracy: This is yet to be determined since I have not conducted my Field Test Shooting review for the KWC Model 226-S5 Sig Sauer. Based on my previous review of the Cybergun branded and licensed Sig X-Five 4.5mm Steel BB version, it should do well with heavy blowback, reasonable power but not a lot of shots per CO2.

Build Quality: Very good, pretty much an all metal construction, good weight and craftsmanship, slide wiggle is minimal, fit and finish is good. As with many of the KWC airguns that use an electromagnetic powder coating, the finish looks great but is thin so it does wear off on the high posts and where metal on metal movement takes place.

Realism: Compared to the real steel Sig Sauer X-Five, the KWC version is pretty close, although it does have a bit different looking slide in terms of the groves or slide serration's, and of course there is no Sig Sauer licensing on the KWC version. You also do not get the ugly white warning instructions so there is a bit of a trade off here and the KWC version also comes with a fully adjustable rear sight which is nice if your aim point is off a bit. Over all the KWC Model 226-S5 Sig Sauer CO2 Blowback Airsoft Pistol is super realistic with its full blowback operation, full size drop out metal magazine and ability to filed strip just like the real steel Sig Sauer it replicates.

  • All metal construction - Extremely good weight and solid feeling gun. As real as you can get.
  • Heavy blowback action.
  • Accurate X-five replica without the Sig Licensing or white warning instructions.
  • Awesome training gun.
  • Both SA & DA with excellent trigger pull, very smooth and light.
  • Has the fully adjustable rear sight for windage and elevation.
  • Nice high capacity full size drop out metal magazine.
  • Fully field strippable.


  • Top loading magazine only.
  • Sacrifice some fps and shots per CO2 because of the heavy blowback but worth it.
  • Finish is prone to wear on the high spots and metal on metal areas 


I am really looking forward to my Field Test Shooting video for this Airsoft pistol, the KWC Model 226-S5 Sig Sauer is a nice big heavy pistol with lots of blowback, right up my alley! I am hoping the hop-up will keep this gun in the same accuracy zone as the 4.5mm Cybergun X-Five version, I may just have to test them head to head to find out? If you're a Sig Sauer fan like me, and require a solid useable Airsoft pistol for gaming or just plinking, the KWC Model 226-S5 Sig Sauer CO2 Blowback Airsoft Pistol should do the job well and at a price point that is very reasonable.
