The Hi-Capa is the airsoft platform. Modular, upgradable, supported by every major brand, and the standard sidearm of UK skirmish and speedsoft alike.

The Hi-Capa pattern started with the Tokyo Marui original — a 1911-derived double-stack high-capacity pistol that became the platform every other manufacturer built around. Today it's the most aftermarket-supported pistol in airsoft. Frames, slides, barrels, hop-ups, triggers, and grip panels are all swappable, and the upgrade ecosystem stretches from £5 spring sets to £400 custom slides.

Length is the first decision. The Hi-Capa 3.8" is the compact carry-style — light, fast, ideal for speedsoft sidearm work. The 4.3" is the duty-pistol length, balanced for skirmish use. The 5.1" is the competition-style — heavier, longer sight radius, the standard length for IPSC-pattern shooting. The 6"+ range is extended-barrel and race-pistol territory, often paired with compensators and red dot mounts.

Hi-Capa pistols are RIFs and require UKARA registration or a valid defence — we verify at checkout. Magazines, holsters, and the full Hi-Capa parts range are stocked separately if you're building, upgrading, or replacing on an existing pistol. New to airsoft? The two-tone range is VCRA-exempt and doesn't require UKARA.

💡 Titan Forge tip: If this is your first Hi-Capa, the Tokyo Marui 5.1 is the platform other manufacturers reverse-engineer from — gas-tight, well-supported, and a known-good baseline that every aftermarket part is designed around.
