Tokyo Marui 31‑Round Magazine for Hi‑Capa Gas Blowback Pistols (Black)

Upgrade your Hi‑Capa setup with a magazine engineered for reliability and realism — the Tokyo Marui 31‑Round Metal Alloy Magazine. Built by Tokyo Marui, a name synonymous with quality in the airsoft world, this mag pairs authentic weight and feel with consistent feeding and field‑ready durability. Whether you run a competition build or a weekend sidearm, this magazine gives you the performance you need when it counts.

Solid construction, dependable feeding

This magazine uses a metal alloy body that gives it a realistic heft while resisting dents and deformation that cheaper mags suffer from. Inside, a high‑tension spring drives BBs smoothly and reliably into the feed lip so you won’t get the frustrating misfeeds that interrupt games. The polymer bumper at the base protects the mag and your gear during impacts and drops, while also making mag changes comfortable and snag‑free.

Designed for Hi‑Capa platforms

Specifically matched to the popular Hi‑Capa pistols, this mag is compatible with Tokyo Marui Hi‑Capa models and many Hi‑Capa clones and variants, including Armorer Works and WE‑Tech models that follow the same magazine footprint. With a 31‑round capacity, it gives you an honest balance between realism and staying in the fight — enough rounds for real‑world reload discipline without the noise and inconvenience of high‑cap winders.

Realistic performance and feel

Players appreciate Tokyo Marui magazines for their consistent feed geometry and real‑steel like behavior. The metal body replicates the weight and balance of a real magazine, improving draw and reload muscle memory. The polymer basepad reduces skitter and keeps the mag seated firmly in the pistol during sprinting, kneeling, and prone movement.

Gas compatibility & safe use

This magazine is designed to be used with green gas (134a recommended) and performs best when used as intended by the manufacturer. Tokyo Marui’s gas magazines are optimized for safe operation at standard green gas pressures.

Important safety note: Modification of green gas or CO2 magazines to use aftermarket HPA fittings or high‑pressure valves will void all warranties and may damage the magazine or pistol. High‑pressure gas sources can cause failures that are dangerous; never alter gas systems unless you fully understand the risks.

Practical tips for long life and peak performance

• Use quality green gas and avoid “super high‑pressure” blends unless the magazine and your pistol are rated for them.

• Keep the feed lips clean and free of grit — a quick wipe and a squirt of silicone oil will maintain smooth feeding.

• Lubricate o‑rings lightly with silicone oil; avoid petroleum‑based lubricants which degrade seals.

• Store magazines unloaded and dry if you’re not using them for extended periods; this reduces spring fatigue and preserves seals.

• If you notice decreased gas output, check the fill valve and o‑ring for debris or wear before replacing the mag.

Who this mag is for

• Competitive Hi‑Capa players who need fast, consistent reloads.

• Trainers and instructors using realistic sidearms for drills.

• Collectors and MilSim players who want authentic weight and function.

• Anyone moving from basic to performance‑grade sidearms looking for a dependable spare mag.
