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.
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.
