Power Source: 12 g CO2 x 1

Trigger Pull: Single action only, which generally produces a very light trigger. On the SW40F it is a bit firmer than most single actions but it's still decent with a short take-up and firm release. You will need to pull the slide back (which also chambers your first round) to cock the internal hammer. After this, for subsequent shots you will not have to pull the slide back as the blowback action does this for you.

Accuracy: When I shot the KWC SW40F 4.5mm Blowback CO2 Airgun from 20 feet out in semi-rested position, I was able to get nice, clean results. I placed 10 rounds within 2 inches, and the shot placement was very well centered. The pistol seemed to keep the rounds tighter from top to bottom over side to side for me. I also noticed when I field stripped this gun that there is a built in hop-up (rubber bar) that sits inside the barrel. This will produce some back spin, keeping the BBs' trajectory flatter when shooting further out. It is also probably there to stop BBs from rolling out of the barrel once chambered.

Build Quality: About the same as other KWC guns. Tolerances seem tight and everything is working as it should. You will get some wear marks (paint wear) on the high spots over time, which is normal on just about any gun. What I like about the SW40F is that the barrel is polished and since this is the first area to lose paint, it really does not matter since no paint is on the barrel.

Realism: This KWC SW40F a replica of the real steel S&W Sigma with the exception of the licensing. You can field strip this gun exactly like a real Smith & Wesson Sigma. All the mechanical parts work the same and I like the fact that without the licensing, this gun is very clean looking with no obtrusive warning instructions on it.

Pros:

  • Mostly metal gun has very good weight to it
  • Accurate S&W Sigma replica
  • Heavy crisp blowback feel
  • Predictable single action trigger
  • Shots were well centered, got good accuracy
  • White dot sights for quick target acquisition
  • No ugly warning marks
  • Full size drop-out magazine holds BBs and CO2
  • Polished barrel and ejection port
  • Fully field strippable

Cons:

  • I only got two magazines in my pre-test for some reason
  • FPS is not super high
  • A bit finicky when loading BBs

Comments: Just like my airsoft review of the KWC Sigma SW40F, this blowback BB pistol was a lot of fun to shoot, with its super snappy heavy slide and ultra-realistic shooting characteristics. It did seem to go through a lot of CO2 very quickly which is not uncommon for this style of full blowback heavy-slided airgun. I don't really mind since it shot well, felt good in the hand , and backs it up with great looks. And heck it's still so much cheaper to shoot than a real 9mm hand gun ;). For those of you looking for something that is similar to a Glock in terms of looks and operation, the KWC Sigma BB or airsoft pistol may be your only real option here in North America now that the Umarex SA177 is history.

Here is my official Field Test Shooting Video Review for my KWC Sigma SW40F CO2 Blowback BB Pistol. Make sure to checkout my previous Table Top Review for more details on the KWC SW40F 4.5mm BB version where I also did a pre-test showing some similar results. My 5 shot Chronograph test resulted in a somewhat expected 285 average fps while my accuracy test shot from 20 feet out in a semi rested position received a slightly wider 3 inch group this time but with most shots being within 1 inch of each other. In terms of shot placement the KWC SW40F 4.5mm BB Pistol shot very well centered but just slightly low. I also only got 2 full magazines this time around so don't expect a lot of shots per CO2 with this 4.5mm BB pistol.
