Velocity: For the chronograph testing, I ran five shots in semi-auto with a brand new CO2 in the magazine. The numbers came in at 293, 294, 282, 290, and 282 fps, for an average of about 288 fps. The spread was tight and the pistol felt extremely “snappy” while shooting, there’s a lot of pop in the blowback and you can feel it cycling hard.

Accuracy Testing (30 Feet): For accuracy, I put a paper target out at 30 feet and fired 10 rounds in semi-auto. After a quick adjustment (the pistol was hitting very low at first), I aimed higher and got a roughly 3-inch grouping. The group was well centered left-to-right, but the pistol was still shooting noticeably low overall. This is the kind of thing you’d simply keep in mind while shooting, and depending on the setup, you may be able to tweak elevation a little (but with steel BBs at short range, don’t expect miracles).

Full Auto (Mag Dump): Then I loaded up and did a full-auto mag dump. As expected, it was basically spray-and-pray at 30 feet. The rate of fire is insane, and between that and the strong blowback, it was extremely difficult to keep rounds on target. I may have only landed a couple hits on paper.

Pros

• Excellent weight and feel solid, realistic, and well-balanced.
• Full blowback provides snappy recoil and realistic slide movement.
• Single-action Glock-like trigger is short, light, and crisp.
• Full-size metal magazine for realistic reloads.
• Semi & Full Auto modes (rare for BB pistols).
• Adjustable hop-up unusual but useful for slight elevation tuning.
• Field strippable, great for maintenance and realism.
• Picatinny rail for lights/lasers.
• Good trainer option for Glock owners thanks to similar ergonomics.
• Minimal branding gives it a clean tactical look.

Cons

• Full blowback reduces FPS and CO2 efficiency.
• Full auto burns CO2 extremely fast.
• Expect maybe one strong magazine and a partial second depending on temperature.
• CO2 cooling effects occur quickly during rapid fire.
• Tight factory tolerances make the first field strip a bit stiff.
• No official Glock markings (a con only if you want licensed branding).

Comments: The KWC 18 CO2 Blowback Steel BB Pistol is a very solid performer for anyone who wants a Glock-style CO2 pistol with full blowback realism and especially for those who want the fun of full auto. The build quality is strong, trigger feel is excellent, the slide operation is smooth, and the ergonomics match real Glock pistols closely enough to make this a legitimate training or plinking option. If you already own Umarex Glocks, this model will fit naturally into your collection and may even share some compatible magazines (listed as AAKC MM19). A full Shooting / Field Test Review is coming soon these KWC/Umarex Glock-pattern pistols are always a blast to shoot.
