Other Gas Pistol Loading Nozzles

Which brands share a nozzle?

• The Tokyo Marui-spec pool (cross-compatible within a model family): Tokyo Marui and the clones built to its spec (WE, KJW, Army Armament, AW Custom, many EMG and SAI guns) share loading-nozzle architecture within a model family. Aftermarket makers such as Guarder, CowCow, AIP and Dynamic Precision list a single nozzle as fitting "TM / WE / KJW" Hi-Capa or 1911. This is why so many parts cross over. The honest caveat: tolerances differ between brands, so a nozzle from one brand may need light filing to seat, and you should always confirm nozzle length and valve fitment when mixing brands. It usually fits, it is not a guaranteed drop-in.
• The KWA / KSC proprietary pool (does NOT share TM parts): KWA and KSC run their own System 7 and NS2 engine, built in the same Taiwan factory, so KWA and KSC parts interchange with each other but NOT with the Tokyo Marui-spec pool. A KWA or KSC USP, M9 or Glock-pattern nozzle is a different part from a TM-spec one, even when the pistol looks identical from the outside. This is the true brand-level fork: identify whether your pistol is TM-spec or KWA/KSC before buying.
