Comparison to Umarex Glock Models
To give this pistol some context, here’s how it stacks up against a couple of current Umarex licensed Glock variants:

Umarex Glock 17 Gen 5 (Semi-Blowback)
• Has the MOS-style removable optic plate
• Features a semi-blowback system with shorter slide travel
• More efficient gas usage, higher FPS
• Double-action-style trigger (not Glock-accurate)

Umarex Glock 17 Gen 4 (Full Blowback)
• Full blowback with full travel slide
• Uses the same style of full-size dropout metal magazine
• Much closer in function to the KWC 18
• Fully licensed Glock markings

KWC 18
• Same full-blowback feel as the Gen 4
• No Glock markings (unlicensed)
• Adds full auto mode, which the Glock 17 models do not have
• Very similar weight, ergonomics, and trigger feel
• Slightly different slide shape, trigger guard, and frame cuts to avoid trademark conflict

If you’ve handled Umarex Glock models, this KWC 18 will feel instantly familiar.

Walk around
The KWC 18 is extremely Glock-like in shape and ergonomics, with only small cosmetic changes:

Slightly longer and differently shaped slide cuts
• Altered trigger guard shape
• Modified rail and frame geometry
• No Glock-branded markings anywhere

Controls are where you expect them to be:
• Slide catch/release on the left
• Trigger safety
• Takedown levers in the Glock position
• Selector switch for Semi / Full Auto just above the trigger area on the left side
• Under-barrel safety disguised as a serial number plate

Sights are classic Glock style:
• White dot front
• White “goalpost” style rear

The full-size dropout metal magazine fits tightly and locks back after the last shot. The slide feel is excellent strong spring tension, clean metal-on-metal sound, no cheap clanking.

Field Strip

Field stripping is Glock-simple:

1. Lock slide slightly back

2. Pull both takedown tabs down

3. Slide comes forward and off

Inside you’ll find:

• Full metal slide

• Return spring/guide

• Removable inner barrel

• Accessible hop-up wheel

• Fire control components including the semi/full auto mechanism

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)

Final Thoughts

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).
