The G series is the most widespread gas blowback pistol in airsoft, and here we collect spare parts and upgrades for the Glock replicas from Tokyo Marui, WE, Umarex/VFC and KWA/KSC. WE's models follow Glock's own numbering, so a WE G17 is a Glock 17 replica and a WE G18 a Glock 18 replica. The range runs from small springs, screws and seals to complete hop-up chambers, inner barrels, nozzle sets and metal slides – everything needed to keep the pistol running or make it more accurate and reliable.
The largest group is genuine WE parts with spare part numbers, down to individual screws, so you can replace exactly the part that has broken. CowCow Technology and MITA supply CNC-machined upgrades such as triggers, hammer sets, guide rods and slide sets, especially for the Umarex/VFC Glock, while Maple Leaf, Dynamic Precision and RA-Tech cover hop-up buckings, inner barrels and valves. AIP, Guarder and Nine Ball (Laylax) offer magazine bases, slide stops, springs and magazine lips, and our own B&W parts give an affordable alternative for nozzle sets, gas routers and magazine lips for the G17. At the top end is a complete metal slide.
What to look for
Manufacturer: Parts for TM, WE, Umarex/VFC and KWA/KSC are rarely interchangeable, even though the pistols look alike. Always check which brand made your pistol – not just the model number.
Model: The G17, G18C, G19 and G26/27 have different slide lengths, barrels and recoil springs. Always compare the length with the inner barrel you take out.
Hop-up bucking: The hardness of the bucking (e.g. 60°, 70°, 75° or 80°) affects how the BB gets its spin. Harder buckings cope better with higher gas pressure and warm weather.
Spare part or upgrade: If a part is worn, a genuine WE part is often the simplest fix. If you want to change the cycling, accuracy or sound, CNC parts in aluminium and steel are the way to go.
